I m25 has a girlfriend who's 23 and we've been together for about 3 years. She has been living in my apartment with me since our 3 month mark because things at her home were very bad and we felt this was a better choice due to me also living fairly close to her university.

I pay for everything, whether it's something that benefits the both of us or something that just benefits her. I also have been paying for her university because I make a comfortable amount of money even though I've only been in my career for about two years. Anyways, recently, for the past few months, my girlfriend has been under the impression that she shouldn't do anything around the house because that's "wifey duties." I ask if she could tidy up around the house since she's free 24/7 because she's on summer break (aside for her part-time that she only works weekends) and she gets upset and says "those are wife duties and that she wasn't gonna give me the whole package without a ring". I ask her if she could make me a quick lunch if I'm running late to work or at least put some ingredients in a grocery bag so I can make it at work and she gives me the same bs about how that's wife duties. It's even gotten to the point whenever I ask about trying new things when it comes to s*x, and she says the same things.

It just keeps getting annoying so finally yesterday, when I asked if she could pick up my dry-cleaning today because I would be working late and once again she replied with doing favors like that are for married couples, I lost it. I told her since doing simple tasks were for married couples then I wouldn't be paying for her next year of university, I wouldn't be funding her activities, letting her use my other car like it's hers, and she would need to start contributing to the house in-terms of bills or she can leave because of course those were things that only husband's did and I was in-fact not her husband. This resulted in her getting upset and claimed that I was manipulative and that I shouldn't hold things that I do for her over her head. I didn't care what she had to say and told her that if she wasn't gonna fix her view on helping her partner out with simple tasks, then I wouldn't help her as well. I then told her that I expected contributions for the bills until then, or I would kick her out. AITAH?

Edit: Thank you for all the advice! Even the ones calling me stupid, which really opened my eyes, and I really appreciate it. I'm just making this edit because it baffles me how some of you guys are assuming I'm using her for sex 🤣. I added how the "wifey duties" thing started affecting our sex-life whenever I asked to try new things. I don't hold it over her head, I just move on and handle my business. When we had our argument, I didn't once bring up our sex life but told her she needed to start doing more around the house and stop being, in my eyes, lazy. Also, to be using her for sex, I would have to actually have sex with her all the time. The rare times we do nowadays are on her schedule, and we just do basic things and then go on with our day.

Edit: Last edit before I plan to have a talk with my girlfriend because she's due to be home from her part-time. I've never wasted her time about marriage. From the beginning of our relationship, I was really transparent on how I wasn't looking to get married until my late 20s or early 30s. From the jump, I've told her if she didn't like that arrangement, then our relationship wouldn't work out, but she was adamant that she was fine with that as well. Yes, I suspect that she's acting this way because she wants me to propose that I've very adamant with not wanting to be married so young. I've reminded her several times throughout the years that if she's not like the arrangement and wants to get married, then she can leave and I wouldn't be hurt.
