It looks like you are ready to move on with your life. If he was just depressed, I would say stick it out as long as you can. But if he is gambling and drinking too, he is not trying to help himself at all and I can see where you would get depressed.
Go with your heart on this. You know your limits. If he is affecting you in such a manner that it is hard for you to go from day to day. You might need to move on. Even if it is a trial basis to see how you can manage. Is there a way that you can do that? Can you stay with friends or relatives for a while? Or do you have the funds to move out on your own?
Either way, I wish you the best.
