He had a long-term affair which ended two years ago. He's never treated me with the same care or affection. Several months ago he stopped using my name all together. He doesn't even use pet names. I've asked him why and he seemed surprised, saying he didn't realize he was doing that. Last week I discovered he's involved with a woman, and also men. My "assumption " is he's depersonalizex me to feel less guilt. He doesn't know I made these discoveries yet. I will confront him tomorrow.
