Time to Leave?

My bf and I have been together two years this week and with every minute we’re together I feel him getting more comfortable… not in a good way. He doesn’t take as good care of himself anymore - I have to literally beg him to shave his face and remind him to brush his teeth and wear deodorant. I do all of the cleaning and when I ask him to chip in he gets annoyed like I’m nagging. There’s absolutely zero romance. We just went through a two month period of him being horrible and treating me badly because he was going through depression and now he isn’t remotely trying to apologize or make up for it. For my birthday, he didn’t get me anything and when that made me cry he got upset with me. I’m losing interest in him. I’m losing attraction to him. It’s weird because on one hand he seems to have no idea I’m feeling this way, on the other hand how could he not.

I feel almost stuck and taken advantage of. One minute he’s telling me not to even speak because he’s doing something on his laptop and I’m bothering him and the next he’s hugging and kissing me. I’m bipolar and have better control over my emotions.

On top of that, I have been having so many wandering thoughts. I think about any and every other guy and fantasize about a life with them. I plan on talking to him about it tonight… but I know he is just going to be surprised and angry. I don’t have any idea what to do.. I just want back what we used to have
