Hi MeandThee29,
Welcome to the board It sounds like you've accepted that even if he gets the help it will require ongoing commitment and will take some time to take effect in a way that directly alters his go to coping mechanisms. From what you describe he hasn't been very consistent in accepting professional help in the past. This must be very disappointing to you and frustrating no doubt. We can certainly relate to that here.
How long have you been separated for? It's great to hear that you feel things overall are going well with you and that your youngsters are getting support for themselves. You've taken some good steps to protect all of your emotional well being throughout this and that's really admirable.
What is tough is that the Jekyll-and-Hyde games continue over the phone. We have to communicate on an ongoing basis because of shared finances. At times it's all lovey-dovey and how much he misses me. At other times it's a litany of all his needs that I failed to meet and what a poor wife I was. He will take a text from me and turn into a major crises if I don't say what he wanted me to say. I always try to cut that short.
It must be difficult having reasons to remain in communication, especially that you are fully aware of how he is able to turn on the charm and this could potentially weaken your resolve. You've taken bold moves to do what is right for you and your family. You certainly seem like a very strong individual.
Now may be a time to consider going LC, which means only communicating about necessary topics and nothing else. It requires a firm boundary on yourself not to get drawn into anything that is unrelated to the issue at hand or is personal in nature. Will the financial link be ongoing or is it in the process of being resolved? There is a useful method called BIFF (Brief, Informative, Friendly, Firm), which you can read more about
HERE, which you may find very useful. I mentally refer to it often when dealing with my son's father. I hope you find it helps.
Love and light x
