I overall agree with the J.Depp comparison. The only and maybe important difference is Puff and Cassie weren't married. This could explain why Cassie didnt initially try to get money.
It could also be that Puff did something to trigger her. For example, him calling himself brother love or the time he mentioned her at whatever award show. Maybe she talked with someone who coached her to ask for money. Whatever her reason or how she wants to see him punished ( financially in this instance) isn't up for any of us to decide.
I also agree it's weird that no one is coming out speaking to Puff's character. The other part is people could be quite due to being guilty of something themselves. For example, no one wants to put themselves into a situation like Mark Curry has done.
If I were famous or even rich, I'd be concerned. In my teens or early 20s, it wasn't uncommon to do things that would be considered sexual assault today. Technically I guess it always was, but most people men or women only really counted rape or forcing yourself on someone.
