I think it is for the best--if he's cut you out of FB and gone No Contact, you really don't have a choice about being friends at this time.
As a "love" addict, it is hard to respect other's boundaries, but it is critical to do for your own recovery and out of respect for the other person.
Maybe try for more "real life" relationships after you do some more work on dealing with the multiple issues you've mentioned here.
A recovering and healthy you is more likely to find a solid and happy relationship with someone who respects and cares for you.
Wishing you the very best helpful. . .
