I am sorry this happened to you and I am glad you have proof to back up your claims. What I do not understand is why you place so much blame on this "other woman", your STBX is just as much at fault, if not more. He let her drag him into an affair. There are women out there that prey on men...married, fianced, single, whatever...yes,even my husband has been hit on. He puts those kind of women in their place. Personally, I would start focusing on your recovery and not revenge or retaliation...it will only slow your recovery down. JMHO. Good luck!
