"I don't feel like it"

So my bf and I have been together for a year and almost two months now. This is my first serious relationship and he is the very first person I have ever actually fallen in love with. But the problem is that I've been second guessing myself. I have severe anxiety and depression and he went into this relationship knowing that and my background. I have tried to explain to him on how to help me get through my episodes, and he's normally pretty good at it. But we got into a fight earlier this year, and long story short I accidentally broke one of the window panes on his kitchen window. (It's like $6 to fix) He lives with his dad bc he's super sick and now I'm not allowed to come over anymore. We see each other less now, and it has become a struggle to get him to come over, much less to stay the night. His excuses are always "I don't feel like it" or he just wants to stay home. Then I'll call him later on, overthinking everything, and he'll be out with friends. I only live 15 min away from him. And I'm positive that he isn't cheating. But then even our sex life seems to be falling apart. I'm usually the one to initiate it and he often says no. I've talked to him about all of this more than once, and he's gotten slightly better but I can already see him slipping back into the same routine. More often than not, I feel like I'm the only one trying.

So my question is, is he just losing interest in me or am I too comfortable in this relationship?
