<human>: Provide a brief overview of the text.

Background: My ex (30/m) and I (26/f) recently broke up after 7 years. I broke up with him- it's a long story, but basically, things had been going downhill for a few years. We were in a long distance relationship, fought all the time, treated each other badly, and he was dragging his feet about marriage (aka he put conditions on me getting a ring). 

Nonetheless, I have not been able to trust him for a long time. While he never conventionally "cheated" per se, he did do extremely inappropriate things. For example, I found out years ago that during the first year of our relationship, he was "cheating" on me with his ex.

By "cheating" I mean that I found evidence that he was skyping while masturbating to his ex (she was on the other end and was naked as well) for many, many, months and I had no idea. He dated his ex for 4 years before meeting me. Mind you about 6 months into our relationship I moved home to Boston and he was in Florida and was continuing this inappropriate relationship with her while saying "I love you" to me. 

I found out by snooping on his computer and found old naked pictures of her and evidence of their Skyping sessions through his Facebook messages. When I confronted him, he denied everything until I showed him the evidence. This really hurt me considering that at the time, he was not a child. He was 23-24 years old. 

So, would you consider this cheating? He never would've told me had I not found out about it. I think of it as cheating but some people do not. I've never really gotten over it and was never fully able to trust him after this. Sometimes I feel like I should've ended the relationship years ago.
<bot>: My ex Skyped naked many times with his ex during our relationship, I want to know if it is considered cheating.
