Since childhood, I've had crushes on my gender (cis female) as well as boys/men. When I was 19, I fell in love "platonically" with my ex-best friend. At first, we'd make out a lot and hang out naked "as a joke" and hold hands constantly/cuddle "as a joke" and sleep in the same bed "just for fun" and pick out mutual male crushes to make out with for no particular reason.

She also really wanted to break up with her boyfriend, or at least said she did, so we talked about that dozens of times, and I finally talked her into a break-up that took and into moving in with me and some other roommates. But eventually, she went back to the boyfriend. I stuck around anyway, listening to her complain about him and helping her break up with him several more times, even going so far as to help her pack and unpack, find rentals, etc.

After many years, she told me I was too needy and she wanted our relationship to be more "light."

I've had one girlfriend and have slept with five women. I've made out with many women. But beyond that, all of my relationships have been with men, and I'm in one now. Sometimes I wonder whether I would have had more relationships with other women if I hadn't been so completely hung up on my best friend for years and years.

My question is, am I bisexual? And was my relationship with my ex-best friend bisexual? When I've tried to talk about this to friends, they accuse me of being straight and just trying to seem more interesting.
