guy came over then didn't want to

michelle
there's this guy i've been flirting with for a while and always wanted to kiss & other stuff and tonight he finally came over just for an hour when i was home alone and all of a sudden i didn't want to do anything. i didn't let him kiss me or anything. has anyone felt that way before? idk what to do and now i feel bad for him bc i lead him on to nothing (in 14 btw)
