You say you don't believe in him, but isn't he already changing? He's doing more for your daughter than ever before, so he does have the capacity to make positive changes. And truthfully, I don't think he's as okay as he acts about all this. He makes a pretty obvious effort to hang out with you.
I think what's going on is that deep down the reason you were okay in the beginning and you're finding it tough now is because you thought it would be done by now, or that you'd be back on track. And so the fact that your H is still talking the talk and walking the walk is a little shocking for you. That doesn't mean the outcome has changed, it just means you need to stop putting a timeline on the result you want.
