I am sorry. That talk was one of the most difficult things I had to do so far in my life. And my S (6 then) did it very dramatic with all his talk and crying and begging...
I am sorry you came to this. Hug your kids and make sure they feel safe and secure. That's what my kids are struggling with. And this kind of talk will come back for sure. Be prepared for that. Stay strong and close to them. They need you both and need to see their parents are OK with what happened. Take care Kalni
