Kimmerz, Because he swings back and forth w/being Mr. Nice Guy and acting a bit immature around your daughter(s), you need to step away from him, i.e., only deal w/him on issues that involve your girls. He's toxic and you don't need that in your life. You've come a long way and you and your girls do not deserve this crazy making behavior.
Step far away from him. He has an addictive personality and you may want to meet up w/an Alanon group just to chat and get some added strength from their meetings. As to whether he's on a "high" right now w/his new family, I would say it will wear thin and he'll become bored at some point and you do not want to become the OW in his new situation.
He's toxic. It's okay to be civil, but don't share anything more w/him except what is going on in your daughters' lives. In his mind, he thinks you are right where he left you and can pick up w/you again and again. He doesn't realize that you've grown and now can see life w/o him in a more promising and pleasant way.
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.
