Hi csips and welcome.
If you mean will he understand your boundary of not being interested in a relationship with him until he shows he is following a REAL path of recovery - maybe.
He just keeps testing your boundary, nothing more.
How about now, will she agree now? What if I go to 1 AA meeting, will she meet me then? How about now, if I go to one more meeting.
Only you can decide how strong your boundary is here and once that is done, stick by it.
As for "ghosting" I don't think that's necessary, if you don't want to speak to him anymore just let him know. I don't wish to speak to you anymore, no need to be cruel about it I don't think? You already ended the relationship, you don't have to continue this conversation if you don't want to.
You didn't Cause it, can't Control it, can't Cure it (the 3 c's)
