So, he's still throwing the silent temper tantrum stuff at you. You've made attempts to talk to him and he's not being civil about things, so...now step back. The ball is in his court to be civil.
If you have pent up emotions and/or anger, then go outside and take a walk or do something physical that will help you relieve that stress. Do not engage in any name calling or verbal tiffs w/him. He's wanting you to pick a tiff w/him to justify why he's doing the things he's doing...don't give him that satisfaction.
You may not be able to break the ice w/him. Don't try so hard that you look like you are pretzeling yourself for him. If he doesn't interact w/you, then cease the chatter.
Stay the course and keep your focus on you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
