Amazing how bright that light is when the hoochie dumps the cheater. And you can be sure this is what has happened.
Cheaters are liars first. You NEVER thought he would cheat to start with, did you?
Unless you are VERY sure of a course of action, do nothing. Let him sweat a while. I further suggest physical as well as emotional distance while you make your decision. Get a third party to be a go-between when he picks up the kids so you don't have to see him. Do not answer his calls, let the voicemail do it. Keep all conversations short and relevant. DO NOT travel down memory lane with him. This will help more than you can begin to imagine.
Without trust I see no point to the relationship. Go back to archives and read.
