<human>: Can you succinctly summarize the text in 1-3 sentences?

I've been in a relationship for a little over 2 years now with a guy I love. Six months ago I kissed a guy at a bar while drunk who wasn't my BF. That's all there was to it - didn't get his name or phone number, left the bar immediately and told my boyfriend. He took me back and we've been trying to make it work ever since. 

I accept full responsibility for my actions. I know being drunk is not an excuse. Before that I really was a great girlfriend. I stood by him when he had a drug addiction. Before I cheated on him that night, I had begun to suspect that he was being unfaithful to me (there was one flirtatious FB message he sent to a girl, and his attitude toward me had become distant. He started to take me for granted, I think. Not to mention we lived an hour & a half apart from each other). I was feeling super insecure. I couldn't trust him very much due to the fact that he'd lied to me about drugs many times in the past... all of these things combined led me to cheat.

Anyway, it's been six months and we've been fighting a lot. I know he hasn't truly forgiven me. We still love each other and we really want to make it work, but he resents me and he never shows me the same amount of affection or enthusiasm about the relationship that he used to (understandably). I know what I did was wrong, but it's hard because I'm constantly making an effort and he isn't. He is clear that he doesn't want to break up, but I don't know...I think we're both somewhat unhappy, despite the love we have for each other. 

Without breaking up, what steps can we take to repair things? Or is it a lost cause?
