I found out that OM have been sleeping with XW and my kids in the same bed on weekends.
I'm absolutely livid about this. No way my kids will spend the night with someone who have no blood relation to them. They are not even married. This something I feel strongly about. No means no.
I am going to talk to XW about this and put my foot down.
This would have drove me absolutely insane. I don't know how you kept composure.
I'm young, probably stupid, and probably would have attacked that guy in your sitch.
