My [34M] wife [34F] is currently 30 weeks pregnant with our first child, a boy. We've been together for 8 years and married for 4 and we're both super excited about it. The other day she casually mentioned him getting circumcised, when talking about the newborn supplies we need to get (stuff for aftercare, not her doing it herself obviously). I asked "Since when did we decide on that?" because we sure hadn't discussed it before, or so I thought. But she said that yes we had, over six years ago when we had been dating for a while and the topic of having kids had first come up, and I had said that I would be on board with it. Now, I should note that I have a bit of (self-diagnosed) ADD and a TERRIBLE memory for conversations, so I don't remember this at all. But I also 100% believe her that it happened. Nevertheless...I feel like I should be allowed to change my mind on this subject and look into it more.
We're having a hard time communicating about it right now, in that I feel like she's not listening to me at all, but I'm also worried that this is going to cause more stress than it's worth. My concerns are about the procedure going wrong and the potential long-term effects on his health, plus I think he should be allowed to decide what he wants to do with his own body in the future. She's saying that she thought we were on the same page about this, and that it's not fair to her because we could have had a longer discussion about it if I'd brought it up earlier, but now it's just stressing her out because she's worried about what else we're not aligned on. So she basically doesn't want to discuss it any more. Her reasons for wanting to do it are mostly health related; her best friend from high school is a doctor and is in favor of it, plus she (my wife) knew someone who had to get it done in college due to some sort of sex-related injury and apparently he had a terrible time of it.
So am I the asshole here? Note that "Get a divorce" is absolutely not an option so please don't suggest that.
Edit: Thanks for all the replies here. There are so many; I'm really sorry if you put a lot of effort into a comment and I didn't reply; it doesn't mean I didn't read it. Honestly...all the talk of mutilation and comparisons with FGM really don't sit right with me. Thank you to all the people who had some empathy for the fact that she's got a lot of hormonal changes in the 30th week of pregnancy. Thank you to all the people who sent actual medical studies instead of youtube videos and random bloggers; after learning more about the medical reasons for doing it I've decided I'm ok with this happening, especially since I sort of already agreed to it.
