I've been with my boyfriend for around 7 months now, and it's honestly the best relationship I've ever had. He treats me better than anyone, makes me feel heard, loved, and cared for. The only problem is I can't get it out of my head that, except for the physical part of our relationship, he treats his female best friend the exact same way as me.
His female best friend, who knows and is loved by his entire family and friends.
His female best friend, who he is currently living with.
His female best friend, who he dated ~10 years ago for 3 years and it only ended because she figured out she was gay (she's currently engaged to a girl from the US, we live in Canada)
I've never been the jealous type, I thought I'd be fine with it when she first moved in and she'd let her thongs hang to dry in the shared washroom, or walk around the house wearing really short skirts, whatever, is her house too
But they have so much history together, so many inside jokes and rituals that I'm just not a part of
And I just noticed this pattern where he would tell me we should do x and y, but then make actual plans with her to do x and y. Example: he has been telling me for a while we should go to a different city for the weekend. A couple weeks ago he had a concert in a different city on a Friday (he had bought the tickets before meeting me) and he planned to spend the whole weekend there, but it snowed the day before and he had just taken out the winter tires, so he had to cancel. We were talking about it and I found out she was supposed to go with him
We had been talking about going to the movies as he has a bunch of free tickets, I was trying to organize something for this past Saturday with this couple we are kinda friends with, but it didn't work. We ended up just staying in on Saturday, I told him we could do something on Sunday and he tells me he's going to the movies with her.
I don't think he even notices this, or how much he mentions her when we are together. I'm not even sure how to approach this topic with him, cause I don't want to be one of those "it's her or me" kinda girlfriends, and I know she's important to him, but this is really starting to hurt me. How can I approach this topic with him? What am I even supposed to say?
