Am i bi-curious? or just bi?

I've been in two serious relationships with guys in the past. The first lasting 5 months and the second lasting 6 months. In the first relationship i thought i was in love with the guy, even though he treated my like sh*t. he cheated on me, and made me feel worthless. With my second boyfriend, everything started out so well, he was a perfect boyfriend, but slowly i started to become less important to him, and he started getting bad habits, such as smoking marijuana, and he would often push me aside or blow me off so he could get high with his friends.

Recently I've been thinking that in the end most guys will treat me like sh*t, and for some strange reason i feel an attration to girls. i feel like the attraction may only be sexual, but i dont know! I have nothing against bi-sexual or gays but thats not the way i want to live my life. I still feel attracted to men, and i still want to marry a man and have a child of my own, but im starting to feel attracted to females and its starting to worry me a little bit. And even though my boyfriend and i have broken up we have recently hooked up and i enjoyed it. And the past few times i have masterbated and brought myself to orgasm i was thinking of him doing things to me. But then when i see an attractive girl i check her out. Im so lost! What am i? And is this normal?
