Questions

My boyfriend and I have been together for 2 years now. Two nights ago, I was really stressed out and we had a nigh fight over nothing and I told him that I wanted to end it. He asked if I was serious, I told him "yes" and that was it.

I called him the yesterday to apologize and he said that we should meet and talk. Last night we met and we said we still loved each other and wanted to stay together. Then he told me that the night before, he was heartbroken and hurting so he went to a bar. He got really drunk and then slept with another girl.

I don't know what to do. How could he do that to me? Should I take him back?

We dated for a year and had the most amazing, loving relationship, all our friends and families agreed. We hardly fought, were absolute best friends, understood each other more than we thought possible and said we were each other's dream bf/gf. He was diagnosed with depression 3 months into the relationship and it's fluctuated ever since then, sometimes getting really bad where he's very distant but he always snapped out of it. He sees a therapist but only every other week. We normally see each other every weekend but haven't seen each other in a few weeks because he was grounded for a while and a few days ago he had a breakdown because he was more depressed than ever and we went on a break to clear his head. He's been even more distant with his friends too. Today he broke up with me because he said he hasn't felt in love with me the last few weeks (same time he was extremely depressed and hadn't seen each other) but he said I was the most special person, he cares about me more than anyone, doesn't know what he's going to do without me. He said he hasn't been happy with us even though he said there aren't any problems and he hasn't been happy with anything lately. He said hed want to try again of he gets better because he wants me in his life and still sees me in his future. People said that since he's so depressed he isn't able to feel his love and that he'll come back when he straightens out. Just days before all this mess he'd say how he's never leaving and loves me so much and I'm his best friend.
