What's wrong with me!?!? Should I just tell him how I feel?!?!?

My best friend is a guy... We went out for a tiny while a couple years back but it was very much a secret and my parents didn't even know. We kissed a few times but that was it. My mum says I'm too young to date and I'm daddy's little girl so it would break his heart but I think I'm still in love with my best friend!! But I'm soo confused!!! One minute I feel like I'm completely head over heels in love with him the next I feel almost regretful about how I felt and I don't even know why I felt like that!! Right now I feel the first one :/.... So I'm just wondering, what do I tell him?? And if you think I should just go for it (I just turned 16 btw) how do I break the news to my parents??
