it just feels like I'm getting a second chance at walking away from the beginning, you know?.
Yes exactly, and maybe that is part of why he is in your life right now. Maybe it is a test to prove to yourself that you are in control of your life again now.
In my case I got closure. I got answers I would never get from my ex. To me it was never about having a relationship with this new person it was about someone in the same boat as my ex admitting to me that they knew what they were doing and could not control it. Or that I was not all of those horrible things that she said I was.
It was a lot of things I really needed to hear at the time.
You kind of sound like you are on the fence with him. A friend told me once, you don't have to sleep with everyone you date and you don't have to marry everyone you sleep with. Took a while to figure out what she was saying, but I get it now.
Maybe he is in your life to help you heal. You don't have to date him to be friends. You don't have to marry him to prove you are not bias against bi polar people.
