I keep being told I am, especially as I've forgiven him and he's the one who cheated. And I know this logically but he is also the one who told me (when she was running around telling our friends that I was paranoid and crazy) and said sorry and who I got to yell at and throw things at and work through my issues with. She has never said sorry once or ever done anything which suggests she feels any remorse.
I don’t want to slag her off or make mutual friends take sides. I just don't want myself or DH to have to be in the same place as her. This mostly came up as I turned down a wedding invite because she was going to be there. No drama and I didn't say that was why to the bride (I faked a family commitment) but a friend I did tell said I was being v U and I should get over myself because the OW did nothing wrong.
