Ok, this is probably your regular "help me help my friend" post. Yes, I know you shouldn't try to redpill them. And I won't, I just don't want to see him (he's actually my cousin, close family) fuck his life completely for a hoe that will likely pierce condoms and get pregnant from him.

A bit of background: they are just 19, poor, and he's battling hard to pay for a college (things are a bit different here, I'm from Brazil). His parents are a bit too religious, controlling but somewhat disconnected from his life. He's naive, tall and cute face so reasonably successful with women despite being kinda lovey dovey.

She's typical: HB8, all cute behavior, but is overly jealous, no dad, mom is a whore that doesn't love her, lots of male friends/orbiters, shallow and explicitly needy for attention. Crazy shit she's done to him include: cheating on him by making out with 20 different guys in a single afternoon, emotional manipulation, dating friends of his just to make him jealous after they broke up, and so on. I in fact believe she's BPD or something.

How can I convincingly try to change his mind without going too far and looking like a crazy women hater? Remembering, he's BP and religious, he believes in soulmates and stuff, and Dark Triad shit is out of question for him.

He's a genuinely cool guy tho, who's building a way to get out of this poor hellhole, or at least to live better here. Help me help him
