My boyfriend of a year has a circle of 5 three guys and 2 females, one of this female is his ex while the other lady is dating a guy from the circle, I’m not always comfortable with this because the two female are bestie, sometimes my boyfriend is with his friends the lady would be with her boyfriend while his ex would be there too because the other lady would say she cannot do with her bestie, sometimes they all go out on functions, there’s not much I can do about it and I’m tired, but my boyfriend says I’m just being insecure for nothing, am I really overreacting
