I should preface by saying that I've been with my boyfriend for 10 months, and we moved in together last month. I knew when I started dating him that he has quite an extensive group of very close friends and that he's a pretty independent guy. That said, I either didn't know, or chose to ignore the fact that he's pretty impressionable when it comes to said friends. When he goes out with them, he hardly ever invites me, and he stays out for a long time (sometimes 10+ hours.) It bothers me, but when I bring it up, or even make an unwitting sad face when he says he's going out, he gets incredibly mad at me, and accuses me of not wanting him to see his friends. He says I'm irrational and unreasonable.
Example: A few days ago, he told me he was going this Saturday to a friend's house to watch a college football game. I was fine with this, said OK, and that was that. Today, he brought it up again, but also mentioned that he'd be there "very late." I must have made the sad face, because it set him off on a tirade. Am I wrong for being sad when he says he's going to be gone all day? It's not like I told him not to go, and it's not as if I was angry at him for saying he was going to be gone for a long time.
I know I live with this man, and I see him every day, but he works and I go to school, and he plays soccer on Wednesdays and Mondays too, sometimes, so when all is said and done, I really only see him a total of 4 hours or so before we go to bed. And really, what I mean by "see" him is we sit on the couch, watch TV, and he's usually in a bad mood from work, so he's not very affectionate. I'm a homebody, and I like to just be at home, but I would also love it if one of these weekends, he just decided to plan to go somewhere with me, instead of with his friends. Why do they get the week's prime time? Why am I not invited? Why does he get so irritated with me because it bothers me? Why isn't it exciting to spend time with me, and why doesn't he seem to want to?
I'd love any advice, even if it's to tell me I'm just being insecure, unreasonable, irrational, or all of the above.
