So i've been with my girlfriend for about 3 1/2 years now, we live together, but she is becoming less and less interested in having sex, spends most of her free time doing mundane things (ie. TV), and occasionally has sleepovers at her guy friends house. When I bring up how this makes me uncomfortable, she just uses the excuse that they have been friends since they were 4. I asked if she would mind if I slept at other girls houses, and she said she would since I don't have any girls that i've been friends with since I was 4. Another thing I've noticed is that 90% of her friends are male, and only 10% of my friends are now female. Before we began dating I'd say I had many more female friends than I do now. I guess I'm just wondering if anyone has any insight on whether or not this sounds like a reasonable situation and what advice you may have. I know TRP isn't necessarily fond of relationships, but I was already 3 years in when I discovered this subreddit, and believe it or not it is harder than it sounds to throw away 3 years of memories.
