I can't tell if I really should leave my partner or whether I'm just feeling a bit 'grass is greener'. Due to awful stuff that happened in a past relationship and things that have happened lately I've found myself totally not able to sleep with him, but I'm not uninterested in sex, I just can't face it with him because he's my partner and kind of expects it. (Yeah, I know, messed up.) I feel like I want to just not do relationships for a while and be on my own and be independent, but I'm worried I'd look back and feel like I'd made a mistake. I think I've changed since we started dating and things I found cute I find kind of annoying now and I feel like I can't talk to him about serious things. Any advice?
