I like to use:
"That must be (must have been) hard for you"
"That seems to be very important for you"
I'm sure there are others.
LOL, Still, I think it would be easy to start a thread on what NOT to say (but would make us really feel good).
Before I got to my present stage, I actually threw cushions at H, and screamed "you must be out of your mind. You are acting like a totally selfish b***d. Totally egocentric, blind to all consequences. Don't you realise how other people see you? How ashamed your children are? As for the selfish cow you are seeing, ask her if she could cook, clean, look after the kids, set up your computer, do your tax return and accounts. She still gets her mum to do her shopping and cleaning. How mature is that?"
Needless to say, it did me no good. It relieved me for a few minutes until I saw the damage I'd done. Wish I'd been on this forum then.
I'd like a thread on what we'd like to say to OW...
