Sounds like many of us are having a bit of an emotional long weekend.
Do your kids not know about you guys separating, or about their looking for a house? Well, I wonder if your H was (is?) still waffling? My H couldn't wait to tell the kids when he left, was almost manic about it. Then he told every single family member and friend. Went out for drinks to celebrate, with everyone that would listen. Was awful (for me)!! Well, at least you have some distance before talking to the kids. I never told them I agreed with what H was saying, though the parenting books said you should give a united front. I DIDN'T AGREE, and I never wanted my kids to think I did!
Sorry to hear about the conversation. Glad to hear you were painting though. Isn't it amazing how a good cry, believe it or not, can really alleviate the frustration sometimes? Glad you are feeling better now.
