Hi Jf, I was going to post on your other thread, but it locked up. So here I am.
It sounds like you have begun to find yourself and realize what you have been accepting for a long time. There are just some people that won't change and will never change. That is a hard thing to admit, when you have been married to someone for so long. You want to help them, then you realize...there is nothing you can do.
Only you can make the changes at this point that will save yourself. I don't see you as a doormat, but a strong, devoted man. Your kids know what is going on and can see how people are behaving. You have kept your grace and dignity in front of them. This will shine more in their minds than you think.
Keep taking the small steps you need to make positive changes for you and your kids. It will happen, you may have to put up with a little more venom for a awhile until things change more significantly. You know how to do that. You are strong, my friend.
