Why. Am I bisexual if I kissed a girl but like a boy?

I fell in love with this girl, and when I finally got to see her, we kissed, and talked about each others felings… we dated for 4days but I couldnt trust her, becuase I knew what she was like, and she got with someone else within the hour. I was heartbroken, but managed to live…

christmas eve, I saw her again.. she told me she had a problem… and she dissapeard for a minute and came back with mistletoe. we kissed passionatly for 4-5 minutes straight. and I gave her a lovebite. the she said, “problem solved” I was over the moon because I thought id never see her again… as I told her, she will always be the one for me, ilove her, but she dont love me anymore. but I also like this boy, he is my age, although the girl was a year older. hes sweet kind caring and good looking. I knows how to treat a girl, and how not to mess with their hearts… I really like him, and I’ve been told he likes me. the furthest we ever went was touching. I never kissed him,, but he is my neighbor so I see him everyday…

I dont know wether I am bi, just because I kissed a girl, and told her I love her because I like the boy… <3 x
