SweetLady,
I used to wait and wait and wait for HIM to do something that would make me righteously able to leave him as well. But, you know what? You don't need any other reason than that if FEELS wrong to you.
"This is not working for me. Therefore I am leaving."
I know it's torturous and you feel tentacles around you, keeping you there (they are guilt, shame, obligation, fear, and worry.) However, as soon as you take the first step, you will find that the "universe" is not against you. Things will begin to happen because you have started the process. Your path will open in front of you.
One piece of advice: Get a good attorney who will make sure you are not taken advantage of. Do not try and negotiate with this person for yourself. You will be treated cruelly.
It sounds like your family is ready and waiting to help. Let them.
