I saw it happen time and time again. A girl is in a LTR with a guy, the girl has beta orbiters and 99% of the time you don’t have to worry about them.
But if the guy hurts the girl or the girl feels hurt due to whatever reason she goes to the beta orbiter to „talk“. She needs comfort and the beta guy is right there, add alcohol to the mix and things can happen...
She will never date this guy but occasionally he may get lucky and make her cheat with him.
How can one prevent this? Something similar happened in my last relationship and now it’s happening to a bro. They regret it afterwards and dont want to have to to anything with the guy but say an excuse like „i needed to feel loved“ or something similar
