Am I bisexual or is this a phase?

im 20 and I became pretty close with a friend 2 years ago, well she is my best friend. I've never had sex with men, so I'm very confused right now, that we broke up 'cause I dont know if im atractted just to her or im bi, or maybe gay. While we were dating I could hang out with guys as can she, but I didnt enjoy it very much. Now, When I see women I dont have sexual thoughts, but I feel something that I cant identify -but has to be a very pretty one, like an actress or model- So I want to know if im bi because I felt in love with a woman or that could be just a phase.
Sorry for my english.. my native lenguage is spanish.

That something could just be admiration. Girls check girls out constantly for comparison and jealousy or like I said just plain admiration. But if you fantasize about girls then you're bi or g*y. But you said that you don't. Maybe the woman you were with just had a certain specialness that would have captured you're interest no matter what gender she may have been (if you believe in soul connections)..not saying I'm some big hippie soul person. But if you kiss guys or at least look at guys and want to touch them then you like guys. Or you could be as*xual (meaning no s*x preference.
