Mopsey, Right now, the things that your h says about his daughter being the only one to love him is just how he feels. Tomorrow, it could be something totally different. Mlcs do tend state just exactly how they feel about things and believe me, listen to what they are saying when it comes to feelings/emotions. They are very hurt and lost souls that have been severely damaged as children and now they are trying to find out the whys and what to do about it as they grow up. It's very sad in many ways.
I think your h was being very sincere about looking for a job that has benefits. In his mind, he's moving on and the divorce won't be that far away. Who knows what he'll end up doing at the end of the day, i.e. he could stop the paperwork at any time, but many don't. They need the divorce in order to move ahead in the crisis and finish it up.
I'm glad to see he's spending time w/your daughter and I'm also glad to see that he asked about his son. He knows that he's made a mess of things w/him. He's still looking to you (mom) to fix things. Unfortunately, you can't. Those two stubborn "boys" will have to work this one out all on their own.
Yes, your h is still bouncing off the walls just like a ping pong ball. His emotions are all over the place. He's not settled down one bit and it's probably going to take a while before that happens.
Mopsey, you are doing great. Try not to allow him to get to you. I know that it's easier said than done, but allow his behavior go out the window and try not to over analyze his every word or behavior. He really is doing everything based on emotions and that's not the work of a "sane" person.
Hang in there.
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.
