Closure won't always be perfect. I had a "closure" call with ex t. She blamed me for our issues, called me names and was rude. It did more damage than healing and left me with some things to deal with. I'm not saying don't go after him or let him away because you should tell him he's hurt you, I guess just prepare he may be in defense mode and out to hurt you. Your T is not your T anymore. He's just a stranger who looks like him.
