Basically the title. My bf is gonna be in the same city as his ex for work and it went from "I want to see him to talk" to "i might spend the night at his house" to "i want to spend a few extra days there just to hang out with him" to "is it okay if we have sex?"

His reasoning also went from like just wanting to talk, to saying hanging out with him would be "fun and interesting"

I dont know. I mean we have an open relationship and I let him do whatever he wants, but I dont feel like he treats me the same way. Like this guy, his ex, I met before I met my bf and we used to be friends until my bf wanted us to stop talking. Over the years on and off he would accuse me of talking to his ex behind his back.

So I just feel weird that he is allowed to fuck this person I'm not even allowed to talk to. Like I get it's his buisness and I'll do whatever he says. But like it just feels like I'm being treated like I'm stupid. It's like his reasoning for things is absolute and infallible but if I say the same things to him he will just fight with me until I have to give up. Like he does something and is like "sorry I can't help it my mental illness" but if I say the same thing he gets angry and says it's not a valid excuse or I'm lying and careless

I've also gone over this is my head, and everything I can imagine is like either I let him do it, or I try to talk with him about it and he gets mad at me and I have to apologize and then he still gets to do what he wants. If I say anything about his ex he can just accuse me of having feelings for his ex and derail any point i am trying to make

So I'm really at a loss for what to do. The only thing I can think of is I just have to force myself to not care and ignore the whole thing
