S,
Welcome and glad you reached out. If you are asking if your boyfriend is a train wreck, yes he is, and nothing has changed, and it will get worse.
Of course he will call you when he realizes that me messed up and you are angry. He will call and tell you he might have issues and should see someone. Saying you might have a problem and doing something about the problem are years apart.
I would step back and regroup. I would completely cut ties with this addict and would get checked for any std's. He is a danger to you and anyone else he is around. I would cut him off all social media, block his phone number, do not engage if he emails you. His life is like a tornado and you are getting sucked in trying to "help" him.
Run and run fast. Seek support with a therapist or some alanon meetings. Ask the question why you would go out with him again, when he hurt you so badly 10 years ago. I think you knew you were playing with fire, but didn't expect to get burned again.....
I wish you luck as he will reach out. You need a plan. Hugs!!
