>>7066015I'm not going to come up with some scheme to fuck in your brother's life and there are reasons for that. First of all, you WILL screw your rapport with him. You can be positive about this. Secondly, men turn off their brains when they are dating someone. It's a common situation that men get warned that their girlfriends are dumb/bitches/insane/just plain old whores, but they WON'T LISTEN. they NEED reality to crash in their face when it's too late to get out of a relationship without getting hurt. Simple as that. Best case scenario she will just ignore every thing you do to "save" him, worst case scenario you fuck up and he hates you forever or as long as he stays with her (he will apologize if he gets dumped).
Plus, you could be wrong and just assuming she's a whore.
The rest of /adv/ won't pretend you're a dude. This is the best advice you're going to get and I'm really willing to help here.
