"I guess that's something that won't change"
(there will not be PROGRESS in anything, but there will be change in the way that it will get worse).
You get the picture, but you don't want to admit it to yourself. The situation is not going to get any better, you're just going to teach yourself to be more of a victim if you stay with him.
What you have to do (for yourself) is...
learn to not love him.
and accept the fact that you can no longer know him.
If not, you will end up an abused wife some day.
Trust your instincts, you know better than to place any faith in him.
