Honestly....who cares? These guys should barely even be in your reality. The less effort you expend on their behalf, the better. If your game is strong and you're strong as a man, not only are these men not a threat, they're not even worth wasting your breath on. Who cares if they want to fvck my girl? Any chode should want to fvck the girl i'm with. These guys are typically in the friend zone for YEARS, and when and if they ever grow the balls to make a move (they usually dont), then she usually rejects them and they get all butthurt for a little while, she laughs with you about how Georgio made an awkward move, you both laugh about it, and either fvck off or start supplicating to her again.
So she has some dude that will go out for tacos with her and entertain her or whine about girls when i can't be with her constantly and he has no chance of sleeping with her. Why is that bad? Sounds like a win to me. These guys have dug themselves into such a deep hole that they will likely NEVER get out of it. We (myself and the girl i'm fvcking/seeing) sit there and make fun of these guys for how lame they are and how bad with women they are.
If she is not even my LTR, i could give a flying fvck who she is spending her time with, or even who she is fvcking. The only time something like this would EVER maybe bother me is in an exclusive LTR, and even then, if these guys are having such an overwhelming negative impact on your relationship, the problem is normally with her if she's allowing these guys to disrupt your relationship, which is really a problem with your own frame because she doesn't respect you enough to treat you in a respectful way, and you decided to get into a LTR with a girl who you didn't vet enough prior and who is damaged and plays games. If your frame is strong as a man, and she respects you enough, she will not allow these men to come between you and her. And if she does, correct it or next her. You probably want to just next her. I would never get into an exclusive LTR with a girl who likes to play games and try to instigate jealousy with guys like that anyway.
I mean i guess you can befriend these guys, but i don't know that i would WANT to honestly befriend some chode dude who just hangs around hoping to fvck her but doesn't have the balls or value to man up and actually make something happen. Befriending them or being overly polite as kind of a defensive tactic is...i just dont like it. Just treat these guys like you would treat any other random ass dude on the street. I'm not going to be fake polite if i don't like them, but i'm not going to actively start sh!t with them or try to tool them either.
