rH, How is your h ever going to miss you if you are texting him? He needs time to process what he's done and will have lost when the divorce is final. Yes, he's a mess right now and there's nothing that is going to change that, not even your text messages. Let him go so that he can miss you and wonder what you are doing.
I'm not surprised at all as to what your lawyer told about the alimony or the amount could be more than half of his salary. It sounds like things are progressing and all of this could be over by the end of the year. I'm sorry that this has happened, but this might be what sends your h off completely on the Mother Ship w/o distraction.
Your h's pain is very great and the alcohol is dulling the pain for him. If he continues down this particular route, maybe he will hit bottom and ask for help.
What are you doing for yourself these days?
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.
