What does it mean when your S is accusing you of behavior he/she is involved with?

Even after a years separation, my W still doesn't want to try and work on our marriage, but that doesn't stop her from getting angry and accusatory towards me when it comes to my private life.

She's having and has been having a EA for some time now, but is getting angry towards me saying I'm having an affair.

It's like she doesn't want me, but doesn't want anyone else to have me. Granted, I've been out with OW who I consider friends, but I'm not having an affair and I'm not interested in one now, but why would she care anyway?

What is this all about?


"It is curious that physical courage should be so common in the world and moral courage so rare."
