>>33282538 (OP)You should leave it. Forget the 'soft surgical attacks'. And also be blunt in what you meant to say: manipulation. You'd skulk around waiting for her to argue with BF so you can whisper sweet reassurances into her ear. Probably driving a wedge between them and convincing her to villainize her BF. Weasel shit, basically. Calling it 'soft surgical attacks' doesn't make it any less weasel-like.
And you shouldn't act like a fucking weasel because you are better than that. If you go ahead with he weasel tactics, you win weasel prizes. What's the weasel prize? A snake. You win a snake-bitch.
Aka you win a girl who can be talked out of loyalty. That's your big grand prize. Yes she would have left her man for (you) and you'll feel a big ego high for a while. Then it wears off. Then you remember she's the type of girl who gives her ear to other men whenever the chips are down. And you will hate her for it. You'll be the next cuck in line. Another weasel will do to you what you did to that other guy.
