.I respect your feelings but you should try to move on instead of leaving her. its not her fault that she can't be with you coz she respect her current relationship. be friend with her and try to be bussy may it will help to distract you.

yeah move on don't associate with her much

you have to accept the fact that she is already your frnds girlfriend. eventhough you confessed, she still wants to be frnds with you, she is treated you the same but you are the one who is changing, soo don't ignore her just talk to her normally but at the same time treat her as a friend's girlfriend and accept that she is not yours , it is very Hard for you to see her with your friend but they are already in relationship and she said it clearly right? accept the situation and move on , don't break any bonds

this comment box is really good this is the same situation now i am going throught but i am in the place of his friend's girlfriend
