Is it worth the pain? He's in cinta with my girlfriend, He told her and he knows that she's dating me. I've noticed that she shows lebih affection to me when he isn't around, but when he is around which is lebih often than not it feels like I go unnoticed atau at least detik best, honestly it appears as though they're the couple rather than me and her. I don't want to bring it up in fear of losing her and I keep telling myself that this pain that I feel almost on a daily basis isn't worth losing her over, but the cold honest truth is that it's eating away at me and it hurts bad, I know that may seem a little over-dramatic but it really, I just don't know how much longer I can deal with this ... any advice?
