>>22978387 (OP)Your brother (Joe?) is a sweet but unfortunately very sheltered guy. Your family kept him "safe" and focused on his schooling, which obviously paid off in professional success. But failing to let him socialize normally has caused him to fall prey to a shit woman. Your parents probably prohibited him from dating in his teens, yeah? So this is what happens; you end up with a super rich guy who cannot discern value in females.
My only advice would be to try and scout a couple of high value women to meet him. Also, try to catfish his wife as some buff looking negro, since that's obviously her type and she should fall for it because she is stupid and easy. Then show your brother the texts and that should end the relationship. He will probably be mad at you too but eventually he will forgive you.
