Bisexuality Support Group
Bisexuality is a sexual orientation which refers to the aesthetic, romantic, and/or sexual attraction of individuals to other individuals of both their own and the opposite gender or sex. Most bisexuals are not equally attracted to men and women, and may even shift between states of finding either sex exclusively attractive over the course of time.
As to your situation, between you and your girlfriend is it love or lust? If she is not willing to be intimate with you would that ruin your friendship, and how important is it to you? It may be better to just be 'close' to her in being strong 'pals' rather than lovers. Good Luck.
