Sorry this will be long, I'll start with a small backstory. My partner (29m) and I (33f) have 2 children, 14m and 6m (14yo is not biologically his however he doesn't have a relationship with his dad and partner has filled those bits since he was young). We got together in 2016, however things got very volatile and we broke up at the end of 2022, amd decided to start trying to make things work again late 2023, by early this year he was basically back with us full time.
In October 2023 my neice (14f) came to stay with us for school, so is generally here from Sunday night until Friday night. Her mum lives about 2.5 hours away so we generally meet half way to swap over. Although he wasn't living here at the time, I discussed with him and she took the bedroom that I/we used, and I/we sleep in the living room.
Now to the main point. Obviously we go through the usual family disagreements/differences, however on Monday it came to a head. We all ate dinner in the living room (the table isn't big enough for so I asked the youngest to sit at the table as it was a messy dinner, while the rest of us sat on the sofa until partner went and sat with him at the table) and I then asked everyone to scrape their plates, my niece was to pack her things as she was going home for the night and then come down and load the dishwasher from dinner.
The older kids took their plates out and partner then took his out and asked them which one volunteers to scrape his plate. They have both said no and tried to get out of the kitchen. He then said to son that he needed to clean his MX kit as he had taken him quad bike racing over the weekend but the kids carried on trying to get out of the kitchen. He then followed our niece and stopped her from going up the stairs trying to force the plate in her hands (I will add that he said he only followed as he thought I had said something to back him up, I was still in the living room). She called him lazy and he called her a gobshite. He then came into the living room where our son was, still holding his plate, and started bickering with him to get him to do it.
At this point it was ridiculous so I stood up and said 'for fuck sake, I'll scrape the fucking plate' at which he snatched it away and started shouting at me that the kids should be doing it. I walked into the kitchen and he continued shouting so the older kids took the younger one upstairs with his dinner. I told him it was stupid and a personal job amd he should have just scraped it. He asked how it was personal and said that it's one thing asking them to do the kitchen, another to take your own plate out and then ask them to scrape it. I did then say would you make a mess in the toilet amd expect them to clean it, as in my eyes yes I would ask them to clean the kitchen/bathroom, no I would not expect them to pick up after me personally. In his eyes he should absolutely be able to ask that because he has taken him racing and does everything for everyone to get nothing in return. Also that he sleeps on a sofa and has given up his bed so does she not owe it him to scrape his plate. With this I then brought up that I don't ever ask him to lift a finger in the house, however he hadn't gone to work that day, slept until gone 1 o'clock, amd when we spoke on the phone I'd asked him to tidy the blankets and sort out the food he'd left on the side, and when I got home from work and picking the smaller one up he hadn't done any of it (he was cleaning out the van from racing, I had made a comment before dinner that I did the blankets for him and we had a joke while cuddling and then I asked him to sort out the food which he did). He then said that was the reason I hadn't backed him up because I had the hump that he hadn't done as he was told and was punishing him. I only brought that up because he said he does everything and no one does anything for him, but when I say he isn't expected to do anything in the house, I mean he doesn't even pick his socks up.
So it's escalated and he then said fuck you, I'll go and you can get on with your evening without my help, at which I told him that I had to drive our niece and wouldn't be back until gone 11pm and would have to now take the 6yo with me, to which he didn't care and walked out. He then spent the night messaging me trying to get his point across and a load of nasty stuff in between.
In his eyes by offering his to do his plate I have undermined and embarrassed him infront of the kids, none of us have any respect for him, he's not allowed to have a voice I'm the house, and he never asks anything so they should have done it. I did tell him I am not teaching the kids those kind of lessons and they aren't slaves, they don't owe us anything for being parents and they do chores around the house as it is. He said something to me about how I am, so I said imagine feeling so entitled that you can't scrape your own plate after you've taken it to the kitchen. Also that I don't want the kids to think that because dad beats his chest the kids should bow down and referred to him as King (his name).
Obviously I wasn't the only one saying stuff and he can be quite nasty when he wants so qe are both saying things but I'm just telling you my part. I would understand if he had asked them to clear the kitchen but in my eyes he wasn't asking for help as it would have been quicker for him to scrape it than ask the question.
I should also add, I don't actually have an issue with the request, it's how he went about it and everything after. When he stormed out I went upstairs to my 14yo son who was sobbing and apologising saying he should have just done it because now his dad's gone. He hasn't come back and it's now Saturday.
On Wednesday, my sister was here as my niece had an award ceremony at her school in the evening, so my oldest had said he would stay home and look after the 6yo. 10 minutes after we had left, he messages me saying he's here and then wouldn't answer. I have a camera in the kitchen so was listening and he had come in and said to our son that he had a choice to make and basically if he didn't agree with him then he could say goodbye to his quadbike. He also sat there slating me to him about how I had undermined him etc amd he would rather die than stay with me but that it'll break his heart to leave the boys again. My youngest came to the camera so I was talking to him while he's telling they were having a chat and his brother was crying. While listening to this my sister is trying to drive us back to the house as quickly as possible to get them and then they are started screaming at each other which got personal infront of the kids as we tried to get them out of the house.
In between all of this he has posted about it on Facebook about how disrespected he is, tried to drag anyone into it that will listen, and has been non stop angry messaging/arguing. My son has asked to see a therapist amd has been so upset all week and is blaming himself as his dad now isn't coming back because I undermined him by offering to do his plate instead of forcing the kids to do it. I genuinely just wanted to save an argument as it was so stupid and in my opinion I wouldn't take my plate out and tell the kids to scrape it, let alone create all of this and walk out on my family over it.
Everyday stupid things come up where I feel undermined but in my opinion they are teenagers and I know this sort of thing happens in every house. He thinks I should have backed him up and spoken about it later instead of saying I'd do it, I think he should have not kicked off at that and spoken to me later about feeling disrespected as I wasn't doing it to be rude. He thinks all dad's would react like this because no man will stay where they don't have a voice and aren't entitled to ask/demand their kids to do stuff for them. I want to teach my kids to take responsibility for themselves when they grow up. So am I the asshole here and would you have reacted the same? He has literally walked away from his family because of this. To add, he has said that yes me may have overreacted but isn't sorry for reacting, as anyone would over being that hurt and disrespected. Thanks for reading and sorry it's long, I tried to get as much in from both sides.
