Ss06, I was around 6/7 when my parents split up briefly. I've written about it on here before, but my mom was a WAS due to a PA. They reconciled after about 6 months and are still together now. I do remember being extremely emotional about the separation.. every night when someone tucked me in, and the other one walked in, I'd burst into tears. But that's ALL I remember.. and it doesn't have any bearing on me anymore.. so she WILL be okay.
I don't know what they used to say to me back then, but I do know that it took years for me to figure out who was at fault (I didn't figure that out until my teens) so they obviously were pretty good at not putting the blame on one another.. I think you're doing a great job to make sure your daughter will feel the same..
