Am I bisexual

Right I have a friend who is a girl (I'm a girl aswell) and well we have been friends for around 6 months. She is the most amazing thing that has happened to me in my life, she is the closest friend I have had aswell even tho it's only been six months we help each other with difficult times. Recently I've been feeling different towards her. Like how I would feel if I fancied a boy, and I just want to no if she might like me because when we meet up we cuddle a lot, hold hands say we love each other a lot and whenever we are together we always catch each other staring at each other. We always play fight aswell and tickle each other and it's mostly her that starts the tickling she tickles my sides and my neck and legs. The other day we was together and we was cuddling for hours outside holding hands and it just felt amazing I wish I never had to leave her so I just want to know do you think she likes me? And am I bisexual? Sorry this is long I'm just really confused thanks xx

Sounds like it's possible that she likes you - maybe talk to her about it?

I would talk to her about it but I'm afraid that it would ruin my friendship I'm just not sure what to do

She's had a bf before but she said it was years ago. I've never really had a serious relationship before.
