We didn't speak about it again, but I was hoping that he would talk to me about it a bit more to at least find out why I was uncomfortable and talk it through, although I figured I'd give him time since his lease isn't up for a few more months.
The other night we went out for drinks my boyfriend and I and he invited her along. She mentioned that they were moving in and he turned to me and said "yeah we're going to be neighbours" (she lives in my street, I live my myself).
I was just kind of hurt that he didn't talk it through with me more and that I had to hear about it like that, and that he didn't even try to make me more comfortable about it by hearing my concerns.
We talked about it afterwards which turned a little heated, and his response was that it wasn't set it stone so he didn't tell me yet. He didn't seem to understand that even if it's just being planned he can still talk about it. I'm the kind of person who likes sharing everything with my partner and going to them about things, so that hurt me.
I don't think they'll be sexually inappropriate or he'll cheat, it's just that they're quite close and have in-jokes and I'm not embarrassed to admit I'd be jealous that he'd see her more than he sees me.
Any thoughts? Sorry for the essay!
