This is true, but the thing is, she was his first love. It was his first relationship, it started when he was 17, I mean, he was still a kid. They didn't even have sex until they were almost 19, and even after that they would do it like once every 2 months or something. It was a kid's relationship basically. Whenever the issue comes up in a conversation (which isn't at all frequent), he always says that it was different with her because he was so young and it was his first time for everything. Which means that he still believed in "fairy tales" so to speak (his words), he let himself go completely, he didn't keep his guard up at all. I kind of get what he means - the feelings I had for the first guy I fell in love with, back when I was 14-15, were a lot more intense and violent. Obviously I feel nothing for the guy right now, but the memory of what I felt for him at the time will never truly leave me. At least, that's what I think right now, 7 years later... for my bf it's only an year later, so I can understand. This also has an impact on his unwillingness to "let himself go" with me, he is still a bit traumatized from what happened. I had years to recover, he had just one for now (even though he's done TONS of progress already). If it hadn't been his first relationship... I don't think I could've stood it.
