My boyfriend refuses to spend a night at my place and for me to spend a night at his place. We used to spend a lot of time together and he would always sleep over at my place. When I asked him why he doesn’t want to sleep over, he always makes lame excuses about things he has to do.
We have been spending way less time together and he always says we will, but his actions don’t reflect what he says. He says he is going through a lot and is trying to figure it all out. I think that’s just an excuse. Should I just break up with him because I think he isn’t interested, but doesn’t want to be the one to end it?

If him not spending the night at your place is a big deal to you, then I think you should for his sake at least. That way he can deal with whatever his issues are without the issues of a relationship too.
Ultimately you should trust your gut. If you think hes uninterested and youd rather end things thats totally understandable and you should do that. No one wants to live in limbo and be unsure of where they stand with their significant other. But he also might just need some space. Either way it sounds like more communication is needed.
