Quick background - I kicked ExH out 4 years ago when DD was 12 and he moved straight in with the OW.
DD generally stays at their house for one night a fortnight but even that stresses her out, and it's affecting her own relationships as she has huge trust issues. I've told her she doesn't have to go any more but she feels that she can't tell him she doesn't want to see him as she doesn't want to upset him. You can almost see the walls she puts up to him when they're in the same room though, she's so uncomfortable around him. I don't think she'll ever forgive him for what he did even though I've told her it was me he was cheating on, not her.
I'm going to have a chat with her tonight about going NC with him, at least for a fixed time to be reviewed at an agreed date, and see if that helps her get her head straight.
Who should have the conversation with him though? I hardly talk to him any more and at 16 she's old enough to express her feelings (and she does, very well) but I don't want to cause her any more grief...
Has anyone been through this and can give me some advice please?
