The thing that bothers me the most is how much danger he put you in. And honestly, I'm a little surprised his girlfriend let him do that to you.
I'm glad that you have this person out of your life, and your plans for the future sound like good ideas. I hope you start feeling better soon. I know that's not easy especially since you're grieving the loss of a 6 year friendship. But you know that you're better off without him.
