Me and this girl have been really good friends for like 5 Years now, all through high school, i think wwe were friends from the 1st month of going to the same high school, and have been friends for a while, i started to like her after a year, but stopped as she got a boyfriend, here is the problem

Lately me and a group of friends went out and she was with us. We were speaking all day Not flirting or anything but messing about, laughing etc, and i do like her,

She is beautiful very pretty, but in my opinion i dont care, because her personality is so strong, looks dont matter on her, even tho she is so pretty. Anyway i like her but dont know if she likes me back, im kinda fat, im 15 and 180 pounds, im confident in my body and trying to loose it but its so damn hard, and if i did say anything i dont want to ruin our 5year friendship we have had sooo many good times,. When we see each other at school we always smile at each other, and everday we speak to one another, we buy each other presents for christmas.

I have had one girlfriend before but i dont know wha to do

Im not the best looking boy around and like i said im kinda fat. 180Pounds nearly 16years old.

We always laugh, and i always tend to make her laugh, i care for her soo much, if anything happened i will help her no matter what, i am never mean to her, i try to get along with her friends, and everything, and even if someone does something to annoy her im still there to defend her even though im kind of a whimp and dont fight. but if it includes her im their telling them to back off.

Please help i really dont know what to do :(
