You’re gonna end up with no friends if this keeps up. Either

A. They start chatting your girl up and feel awkward around you. Those are guys that are uncomfortable with the dynamic. They probably think they’re getting one over on you. Also if feelings develop these are the cowboys that will try to break up your relationship.

B. Friends that your GF sexually rejects. They’re likely to feel awkward after and avoid you both.

C. The “good ones” that maintain their friendship while seeing your gf but eventually break up with her. They’re likely to feel awkward after and avoid you both.

D. The guys that reject your gf. Guys tend to hard avoid women they turn down, when and if it happens. They will likely avoid you both.

E. Guys that remain platonic with your gf. These may actually stick around, unless their are closely tied into a social network with groups A-D, in which case don’t expect any invites to group outings.
