Please see that what your H is doing has nothing to do with you. When you get a chance go back and read through your thread. Your H has been all over the place. He's suggested things that make no sense whatsoever. His brain is so jumbled it's short circuiting and he can't even stay on one train of thought through to completion before he's off and running again.
Does your H always seem to be in a hurry even though you know he has no place he has to be? My H can't sit still and is in constant motion. He just seem to be totally uncomfortable in his own skin. I believe he is like that because he's trying to outrun his pain, unhappiness and guilt.
As Snodderly said, the best thing you can do for your H and yourself is to let him go. God will take care of him in His time.
You're a smart, courageous lady. Look at the life you have built for you and your kids! Protect yourself financially and you will be just fine while your H is away on his journey. Take this time and make the most of it while you figure out what you want.
