Hmm.. I would want to know why they were on an off for 5 years, but also this all says RED FLAGS. He is in recovery and JUST out of long-term relationship. I would steer clear of this man. You would have to deal with him being a recovering drug/alcohol addict and on the relationship rebound as well. Unless he has been in therapy for the last 12 years addressing his issues, and has a good handle on his health/mental health that led to addiction, this spells trouble for you. Surely, there must be other more eligible singles to date.
