Why are there positive changes when you're halfway out the door? Because there's always that chance that you might actually do it!
I think deep down you know that yourself but have been afraid to do it. But if this keeps up, there won't be any changes because he knows you're bluffing!
From the sound of it, it's he that wants you to move out? Quote "He threatens when is say our relationship isn't working by saying I need to go find a full time job and move out bc he wants it to work so he's not leaving or giving up.
You just might want to go and find that job. At least you will have that security of knowing that you will be OK if things go badly and you wind up separated or even divorced.
Also, think about how you WON'T have to go ask him for money when you need gas for the car or buy a little something for yourself. Wouldn't that be a nice feeling?
That may also give him a reality check in that maybe you're taking the first step in being INDEPENDENT and actually going through with moving out.
