IB, I think all WA's say that the kids will adjust and be fine.
I work at a school, too, and deal with kids from broken homes everyday. I see the damage it does.
My H, and I, also used to talk about what a D does to kids. We both were on the same page about the harm that it causes.
Now H says that they're not the first kids to go through this. They'll be fine and just need to grow up about it.
Well I hope that ow was worth it because even though they still love their father the kids no longer respect him. S23 hasn't spoken to him since he left 9 months ago. Personally, that would devastate me, but I guess I'm just wired differently.
