I feel like the best way to react would be total apathy. But at the same time it seems a bit beta to be so passive about it. Especially if she mentions something about like how tall he is (and you're short) or his dick size (and yours is below average) or if he's rich (and you're poor) etc.

A lot of the alphas I know IRL are the most jealous, possessive, aggressive types ever. And their women respect and admire them for it. Especially true for the older generation, I find.

Does saying something short and to the point like "I'm not interested in hearing about you with other guys". Come off as needy/beta? I've been treating these discussions as shit tests and just replied playfully. Not sure whether that's the right way of going about it.
