It isn't really jealousy yet because you don't have another guy you are interested in. What he is doing is searching for reassurance from you that there is no other man involved. He then feels better and then can keep the upper hand with you...
Your best bet to get this man to turn around is to PUSH for the divorce and tell him you are done. Keep going out on the town. He needs a crisis of MAJOR PROPORTIONS. That means he needs to feel you are done for good. Not just one day or one week, but for a few months.
