In a recent OP a fair share of men stated they've always cheated on their SOs.

They also implied that their ideal situationship is a relationship where he gets to have sex with other women and she must remain faithful.

That's his prerogative and if you were to ask him I'm sure he would say it's "his natural biological imperative."

My question is for men who prefer that lifestyle, is she within her right to branch swing at will at the slightest chance of a better offer?

Most women temper any feelings of branch swinging out of loyalty and respect for their partner. However if her partner is cheating or wanting her to accept his philandering, she's going to be less likely or even encouraged to indulge her "biological imperatives."

Scottie Pippen and his wife are divorcing after 19 years and 4 kids because she allegedly fucked Future. He's always had rumors of infidelity. This appears to be her first. Seems to me knowing he had no desire to temper his "biological imperatives," she finally felt no reason to temper hers and went for the presently higher status guy.

I find the whole "biological imperatives" logic an excuse and a slippery slope to both partners being their worst selves.

Question also applies to women who hypergamously branch swing with impunity. Does a woman like that elicit sympathy if she learns her husband had cheated on her previously. Or that her new husband cheats.
