28 yo guy here, been going out with my girlfriend for 3 years now. In my social circle, i have noticed that there are 3 different girls who always talk to me, hang out around me etc when i'm not with my LTR, but when shes there, they hardly even say hi, and focus on my LTR or other people in the group. Am i just reading too into this or is there some sort of reason for it?
