I would suggest counseling for both of you individually and together, but I bet his reaction is not pleasant and it wont happen. You can try though.
His "in my face" behavior WILL eventually lead to something physical. He is a ticking timebomb and for some reason you are his "venting" object.
I dont know why or how they can keep it together and walk away from other people when they are soo quick tempered with us.
My advice is if he unapproachable...absolutely do not continue with the conversation. You probably do like I did and continued because you TRUELY wanted to know what the problem is for reasons to work on it. But he wont see it that way. Everything that he walks away from daily will come out against you one of these days.
He needs help. If he refuses, it wont get better. It gets worse.
Mine, in the beginning, would never come out and say he didnt want to be with me....but did the blowing up and leaving. Im starting to think he wanted to leave permanantely, but wanted ME to do the "ending". Just like you and others may see him take the high road with others.....it may be his pattern to make the other person to be the bad guy to make him look like a victim.
Listening to what you put up with at home with him.....I cant say that his ex has no reason to be upset with him. She has probably seen his true colors.
I dont know what else to say other than you got to take care of yourself and make decisions that will take care of you. YOU CAN NOT FIX HIM WITH LOVE, PATIENCE, SPACE...NOTHING. ITS SOMETHING HE HAS TO DO AND IF HE IS UNWILLING...HIS LOSS.
good luck
