<human>: We have been dating for 7 years. We broke up because we kept fighting about really small things and both got fed up. Looking back, we both laugh about how small they were. They are easily fixable and we see that now.

But here's the problem. He had sex with another woman while we were broken up. In fact less than two months after we broke up. This hurts my heart because we have only been sexual with each other. He told me he was depressed after we broke up and having attention from someone else was nice but is even more depressed now because he had meaningless sex with a girl he's not even dating and two because he felt empty without me. 

I asked why he just didn't ask me back (he broke up with me) and he said it was because he felt guilt that he stooped so low and had sex with a woman he barley knows. It's eating him up.

I know I shouldn't feel betrayed because we were broken up. But I can't believe he did that. It hurts me so bad but I want to forgive. I want to get past this because we love each other.

I know that I can't be mad because we weren't together. But it really is completely out of his nature and makes no sense. I'm honestly shocked.

He's telling her tomorrow that they can no longer "see" each other because he wants to go back to the person he cares about (me). It's just really surreal.

Condense the text into a few key points
<bot>: Ex had sex with someone else while we were broken up (casual sex is completely against his morals) and said it was because he was depressed. How do I get this burning image out of my mind?
