Another question.... I bet she comes home this weekend and asks for a separation. She won't admit to the A but will say she needs space and time to think. She'd likely will say that because I don't trust her proves that we need to separate. Should I agree to the separation? I assume yes.
As I stated in my previous post, I'm not sure if your state offers a legal (formal) separation or not, but speaking generally your reply is "I don't want a divorce, and haven't really thought about a separation, but if you want to leave I will not stop you. I'm certainly not leaving, and nor am I going to allow the kids to leave."
But this is where you need that legal advice we were discussing yesterday.
