I kissed a girl and i'm straight

I met this girl and we become really close. she really understands me and we have so much in common and she's not straight. but i was with that guy who completes me in all ways, i really had my best moments, hrs, seconds with him. but he never appreciated me. or maybe he did!
anyhow, we broke up...he cheated on me. and i told him from the beginning of our relation 'do not hide anything u do that affects on me negatively' and guess what? he did!!! screw it
i decided to not go out with any guy whoever he is. because i've had enough of cheating, hurting,and unappreciated treatment.
so i like her alot, and she likes me too. we kissed :P. i felt so weird, but i never want to end up my life with a girl. i really want to have a family one day and live my entire life with a "REAL" man. not an a**hole. IF I FOUND ONE!
i want to know if what i did makes me lesbian or bisexual or what? im really confused. but i was doing it cause i felt like doing it, and i like her, but im not planning for sex. no way i don't even like it. though, i never tried it before! THOUGH the idea makes me horny lol :P. but i just feel so good and a real human with her. is it that wrong?
is it normal doing it? is it normal to kiss a girl because you've had enough from guys bad relation? is it normal to turn this way just because some bastards f**kers affected on you really badly as you see? and im afraid of what if i met that "real man" and then he rejected me for having such experement or whatever with a girl? am i abnormal :S?
need some real and serious advices
