You certainly have lots to think of here. The only thing I can add is that Gucci is right in that if there is the thought that they have lost you they suddenly want you again.
My H tried to act as though he didn't care if I went and met someone else, said it wouldn't worry him. A few of his close friends kept telling him that they knew he could never live with that thought, at that point his jealous streak kicked in and that is when the hissy fit started because deep down he knew they were right and I too knew he would not take that well - Gucci was correct once he thought he was going to lose me, he chose me and chased me.
One thing my H said to me was that he respected the new found confidence and respect that I seemed to have developed.
