My DP cheated (long story) and he has done all the things I asked (lots of hoops to jump through) but it's transpired after we went through things over many months that he has some kind of feelings for the OW.
I was led to believe (or he says he genuinely thought at the time) that he felt nothing for her and it was a huge mistake, but over time it transpired she was someone he felt something for.
This has hurt me worse than the affair, as I was able to "move forward" as I believed he loved me and only me and that was something I was able to live with.
Now it's become clear, many months on, that he felt a loss / missing her. He says he doesn't love her, but felt something, and that's made me feel like I want to leave him.
He's made it obvious he loves and wants me more, but the fact he felt anything at all seems to painful. If someone truly loves you, surely they couldn't possibly have any sort of feelings for someone else?
