Male friend in his forties keeps hooking up with girls in their early 20s.

I (37f) have a childhood friend who is in his 40s and keeps trying to get involved with girls in their early 20s. It makes me feel sick honestly, and I’ve tried telling him to go for more age appropriate women but he’s always full of excuses, like once these girls meet him they tell him he doesn’t act like a 40year old at all (he goes clubbing and does molly etc with them). I’ve been through the gamut with men so this kind of thing is pretty triggering for me, but he insists on telling me like he has no clue how creepy it is. I’ve tried the polite way out of spending time with him but he is so clingy and relentless. I’m debating whether I should tell him off about praying on young women and explain this is why I can’t be friends anymore, or should I just ghost him? Would really appreciate any advice
