Coming Out Support Group
This community is dedicated to the challenges that gay men and lesbian women face, both between the partners in a relationship and from other influences (family, society, etc.). Find support and talk to others who may be facing the same challenges, and share your experience.
Sorry about the breakup, I know they suck. As for being bisexual, well give it time. Everyone in their teen years goes through a period of sexual discovery. Let yours happen naturally, don't force it on yourself. If you feel drawn to a girl, great. If you feel drawn to a guy, great.
I can tell you that rushing out of the closet when you aren't even sure yourself, helps no one. There is no need to make your process of self-discovery a public spectacle, so if and when you come out, it should be after you've learned more about yourself. Might I suggest not trying to cram yourself into some label like gay, straight or bi. Just be you. Follow what feels right and let the naming of it come second.
