Maybe try and look at it from his side. He is an INFJ who has made a decision may debate the wisdom of that decision everyday.
I'll tell you from my viewpoint a similar situation. I stopped seeing a very very good friend several months ago and we have not spoken or seen each other since. For two people that spent much of their day texting each other, going on road trips and shooting the shit it was phenomenal to just ... stop ... contact.
But I made that decision and after several weeks of soul searching have recognised it is the best decision going forward.
Guess what? That decision doesn't mean I don't hurt still EVERY SINGLE day. That I don't think about this person EVERY SINGLE day. If this person contacted me now, after all the pain I have been going through and slowly getting back to living a life without them, then I may well explode as well. Its not because I don't want to see them. Its more (for me anyway) that I have done so much work to reconcile my feelings for my decision and start restructuring my life that I cannot bare to be reminded again after all this time. To go back to that place that was just post breakup. To be reminded of your decision, your possible mistake. Hundreds of things in fact.
So my point after all this is, don't think of that person as different to who you thought they were. Cherish what was, and that people react and think differently when ceasing a relationship with another person.
