I see my friends Bridge and Scookie have waded in to help you out of the FOG (fear, obligation, guilt).
If you need motivation to get out, think about your girls (I couldnt' see how old they are) and what you are teaching them about relationships. Your daughters deserve better. It doesn't matter that you have sorta been down the divorce part before but you hoped that it would get better. Don't worry about feeling ashamed about that. Feel the feelings and then put them aside like you are looking at a rock specimen in high school. then pick up the next feeling and do the same. Move forward.
Your h appeared to try for just the 90 days that it took to hook you back in. It was not your fault that you trusted him to care for you again. Look to your family for support if you can. If they fancy themselves above you by saying things like "I told you so" then simply say, "yes. will you support me now?"
Now, however, you do have a choice in how you live your life.
Fast forward 30 or 40 or 50 years to your deathbed. What do you want to have done with your life? He does not appear to be valuing you as a wife. You are not valuing him as a husband (I don't blame you one iota btw). Something has to change and the only thing you can control is YOU.
Big hugs...... I haven't been to the depths that you have but it felt pretty cruddy where I was so I hate to think how you are feeling.
