Wow! You've made a lot of changes. Does he seem to like all the nice things that you are doing?
He seems to want reassurance and to be forgiven. Has he asked for forgiveness? I do think until someone shows real remorse and asks for forgiveness, there is no point in giving the forgiveness. That's like giving a gift to a person who does not want the gift. It only has value if the person wants it.
I would not try to move too fast. Opening up the communication is good. Try to keep it at a level of trying to understand each other. It can be too much to try to negotiate how you will act to each other. If both people just make a good effort to understand the other, then acting well together can happen naturally.
