Hey guys, to make it short. Ive known her for yrs now. Since i was 12, (im 19 now) and she's (24). She would of sometimes come with us in the hotel when were staying there for a vacation. she would give me no little attention as i was a loser back then. The problem is, i have above average looks but was very skinny as a kid, had zero fashion sense and low self esteem . But that change when i enrolled my first gym, gain some pounds and dressed better. Now, she would give me looks. Compliment about how i dress better now, how i gain a couple of pounds. So, how do i hit on her?

Sorry for my bad english as english isnt my first language. P.S (She has a boyfriend but they would occasionally meet once in a year)
