No, this was fate offering him an olive branch - a chance to finally have them for good. He wasn't willing to ignore the opportunity... and if he had to threaten to destroy their life for it, well, that was just him multitasking.
mhm.... basically, I haven't defined how user and Ghost met or anything important from their past. Just that the two of them have sex from time to time and have a troubled relationship.
so, yes. he's a pathetic man who hasn't gotten over a relationship that never existed. blackmail is just a love language <3
