What is bothering me most, is do I tell them about the OW? I have decided we should separate (he wants cake & eat and doesn't agree but is reluctantly going). Concerned that I will appear to be the bad person forcing Daddy to leave.
I think at the ages your children are, you can't really pretend it's anything other than what it is. I would just say that he has another partner and you are separating. How did he have an EA for 8 years? Or is it just that you can't prove affair and he is lying?
