Look hon, you don't need no confirmation. You need to just listen to your heart and kick that ***** to the curb.
For me, my confirmation is the day that trust went flying out the window. That's all I need. That's all anybody needs. If someone is acting shady...that's good enough for me.
You just need to let it go, embrace the future without him. Kick fear in its face. By reasoning, you are a whole hell better off without him years ago. Why is he still there?
Here's hoping that you do the right thing by your children.
