Why is she doing this?

i am the shyesh type my self and once this guy had a crush on me he wasnt really shy but akward and he wasnt really fat but round..giggle.. he asked me out but we'd been friends for so long i didnt want to ruin it so it kinda made me mad him being so persistent and all which would put in thoes off days. I'd say you should wait that next year cuz I realise we really could've had something back then mabe even know but he's gone..
