Things will turn around for you soon. I have to believe that for all of us.
I think you need to stop turning to him for support, even for your son. He obviously is uncapeable of that and all it does is leave you rejected. He isn't being a good father at all. If that were my son in the ER, I would have been all over it to get there. He didn't seem to want to be bothered. So, before he has a chance to reject you and your son don't even call him. Same goes about anything else like the car situation. He won't be there. Its just disappointing you.
I went out of town for a few days and had such a good time. It didn't stop me from thinking about WAH, but it did slow the process down. He was on my mind maybe only 50% rather than 90%. Keep busy. Blow exH off, when and if he wants to be a father then he will contact you. Right now its not your problem.
Hang in there.
