As tough as it might seem, I think you need to stay the course. Although you don't seem to be seeing the actions that you feel you should, things do take time. My question to you would be, "Do you feel these changes are sincere, or are you suspect of them"? Obviously there does seem to be some trust issues. I guess my feeling here is trust is something you owe yourself. In other words trust others as a gift to yourself. Nothing tears a person down more than going around not trusting others. How are you going to live with anyone when there is no trust given or received.
