It seems like your a bit confused about whether you are bi or not (I've never come across thats its a 'decision' that people make lol), so what I'd suggest is to experiment and see how you feel about the issue...
If it seems that you are then heck, SO WHAT! It shouldnt matter what other people think about it! And if your friends are true friends, then you wont have to worry about what they think
Good luck hun,
