Which one do you think is going to initiate the divorce? The obvious choice that comes to mind it Anisa since Ian's balls have shriveled off, but I don't know...
Ian still has efame despite being irrelevant. If a much more attractive, sane, un-tattooed girl came along do you think he would upgrade? Or is his spirit too broken?
Either way, the marriage won't last long. Marrying a woman who sells her intimacy to other guys is like building a house on a rotten foundation. Add the BPD and it puts the house next to an active volcano as well. (And from Anisa's angle, marrying a dude who doesn't mind pimping you out isn't smart, either.)
I have the feeling the marriage is already crumbling but they are still presenting a false happy narrative just to spite the haters. They seem like the needy types who won't exit a relationship without an illicit lover holding their hand through the process so I guess at the moment we're just waiting for the right person to come along.
