He was never like that when the relationship started. It slowly started dwindling down about a year and a half into it. I understand that “honeymoon” phases end, but the change is too extreme to ignore.

I’d also like to side note so nobodies heads go there, that he would never cheat on me. We have both had crappy people in our pasts who have done that. That’s one thing I can always find comfort in and don’t worry about no matter how bad things get.

No we have never discussed it before. It’s hard to explain but we know each other very well, you really get to know a person and and the unspoken boundaries with stuff like that.  Which is why I got the reaction I did and why he was so upset that he hurt me.
