So I've been dating this girl for a few monthes now and I really do like her, a lot.. but recently she told me that her best friend likes her and that she likes her back... yes her best friend is a girl, and my girlfriend used to and still is bi sexual... needless to say I would give anything to stay with my girlfriend but I just don't know what to do :/ someone please help me

I just feel kind of helpless here and don't know what to do..

Its quite complicated... I thnk you should giv hr an option to choose between you both... because if she loves you she will nt leave... n if she doesn't... then wats the fun of being with tat gal..

Well you should see if she likes you more than her or if she wants both then you might get a lucky threesome. Lol but seriously you don't want to be with a person that is starting to trip over other people it will just end up bad in the end.

Same situationn happened with me, don't make her choose. You'll get the complete worst answer that you could possibly want. If she wants you both ask to have her share and make sure that's what she wants. Most girls will choose the guy as long as they don't get too controlling.
Honestly, girls are annoying and too dramaticccc. Shell be back to being fully yours and love you more for giving her that option :)
