It could also be that they still aren’t that emotionally mature and when they turn 25 they realize what a weird situation they are in and thus leave him. I do think it has to be a mutual agreement. It’s too tight to be a coincide and thus far Leo has never been in any scandal or negative comments about the relationships and he is still friends with a lot of them. So, it’s weird, but not in a “creep abuser” kind of weird. I just think he is emotionally stunted from so much fame and power from an early age. It fucks up social development.
I love this graph because of how succinctly it summarizes info. But I also hate this graph because it is missing like 10 or 15 other women he has dated of several ages that break the neat pattern. Also, it hides how only like two of those relationships were truly serious, the rest are gossip and tabloid speculation from having seen him “next to them”. It is all very speculative. He does have a weird thing for younger women, but I think that part of it is that most single women on his social circle are going to be aspiring and upcoming super models.
