What is his deal? Is he trying to hurt me more by showing me our marriage was so easy for him to get over?
You basically answered your own question. His widdle ego is hurt that you had such conviction in D and not wanting to R.
So, he is lashing back out at you like a child having a tantrum.
My oldest son basically ran away (he was 18) from home. He went off to college in a mantrum. He wouldn't take calls (we only made two and then stepped back from the situation) for about a year. He talked about how much fun he was having, he spread lies about us as his parents, and made it a point to compare how much happier he was now that we weren't bossing him.
In reality, he was sad because he thought his family didn't chase him enough before giving up. His feelings were hurt, he acted immaturely.
Lesson: People that are truly happy don't have to announce to the world how much better off they are. When one is truly happy, they are at peace and contented with just being.
Ignore him like the child he is acting like. Don't let him know his behavior is hurtful, that is exactly what he wants. Carry on with the D proceedings as if nothing were amiss. He will act out worse at first. Then, as he sees his actions get no response, things will calm down after a while.
In time, his actions will declare loud and clear that you are better off without this childish individual. You will see that he wasn't worth all the hurt.
