Wait and see......it will help him build trust with you, and it will help you to move slowly in the right direction with small changes. The worst thing you could do is jump right back in right now. You sound like you have it all under control. If/when you ever get to the point where you decide to get back together, require absolute FULL transparency from him without him getting mad at you for it and any and everything you need, including him reading books, counseling, etc. EVERYTHING.
