I've named changed for this, I'm a regular poster and lurker and my DP knows my normal username. I've changed some details slightly to not out me
A few days ago me and my DP of a few years (we live together) were talking about the past and he admitted he cheated on his EX numerous times throughout there long term relationship, before they had there DC and after. This shocked me, I knew he had a bad relationship but didn't think he was like this. He isn't bothered and said the relationship was miserable neither of them were happy they argued all the time ect ect so he cheated she never knew so weren't hurt even though he knows it was wrong to do but he doesn't regret it or feel bad.
How can he not feel bad? It's changed what I think of him. He's told me he's a different person now we have a different relationship and he would never do that to me but I don't think I believe him.
