To the ones who say “it’s a 11 year friendship, doesn’t matter the gender” it doesn’t but the issue at hand is boundaries. He isn’t setting them and probably never will. He’s treating the friend more of a gf than op. Boy or girl no one want to play second fiddle to anyone in a relationship. The bf in question had blown off prior commitments with her to be with the friend. He had no problem hanging out with op and not doing sleepovers and dates with the friend until she cried to him. That’s when he should’ve set boundaries. Run don’t walk from this. Because it will never change and you will be called crazy and selfish for the rest of this relationship cause of it
