I’ve had this issue with multiple girlfriends (who all ended up with one of the guys I warned them about).

It sounds like you pushed them away to me: These other dudes will have been being nice and friendly to her meanwhile you’re being controlling and untrusting of the very guys who are considerably more fun to be with whilst you’re telling her which of them definitely fancy her, so she’s in if she wants to take a punt on one of them.

I mean, you’re kind of acting like an annoying wing man for her male friends. Why not swap you out?
