I am glad you enjoyed your love-bombing. It is genuine in a way. They really do wish you would abandon all else and come back to their self-imposed prison. I am confident I would get the same treatment if I went.
I also don't hold anything against them when they cannot attempt to "love" me by inviting me out to coffee or lunch if they miss me so much. They are in a cult. It's in their reprogramming.
Glad you enjoyed seeing some old friends.
