Affair is over and WW is responding

[Hope4us]

I think DS15 is going to need stability in his life and IMHO, that stability is in the family home. I don't have a problem with him seeing her anytime he wants.

We'll just have to see what he thinks when I tell them the truth about what's going on. I'm really looking forward to the look on her face when we get home tomorrow and DS15 says "you're having an affair and don't want to work on the marriage and want Dad to leave the house?" Let me strike that. I'm not looking forward to any of this, but she's really become the most selfish, self absorbed person I think I've ever known.

I really didn't want it to come to this. But there is no way I'm moving out and going to pay her alimony and child support so she can continue the life style she's accustomed to while continuing her affair. She thinks she's going to keep living in her nice house etc, continue her affair and when DS15 has graduated from HS continue on with her "perfect" life.

I'm calling a lawyer right now.

Edited to add: And my brother thinks her response sounds like a lawyer told her what to say.
