Think of this as you two beginning to date. Ya, I know your married and this is not being married. All to familiar with the thought process. But, focus on quality time. Have you by chance read The Five Love Languages by Gary Chapman? If not do so.
You both have history to work through and that will take time. The mind, his and yours, simply can't turn off. You will have frustrations, as will he. You are frustratred because of your expectation of him to do what you want him to do. Which is recommit. He simply isn't ready.
This is your time to shine. You have turned him around. He is no longer running from you. He has stopped and is processing what he is seeing. Adopting a genuine, friendly and positive attitude and showing him the new you will work wonders. BUT DO THIS FOR YOU! Not for him. These changes are yours, not his. Rediscover the sj, YOU want to be.
You stated earlier, you were argumentative and confrontational. Is that how you want to be today? What will you do to put those discriptions behind you. If you focus on you, you can not fail! Improvement will come with the effort you put forth. This is by no means easy, but it is worth every effort you can muster.
