So me and boyfriend went to da movies like an ordinary couple you kno laughing talking hugging kissing cuddling nd stuff through da movie but when da movie was almost ova he asked can i suck/lick ur boobs? i said no so he asked why nd i said cause we are in public so he said so nd i still told him no. then after dat he moved to seats down from me and i followed him nd asked why was he mad i got no answer. so we left out cuz da movie was ova nd my riding was coming so i went to give him a kiss nd hug goodnight but he shoved away so i just left nd i tried calling/txting but no answer..... WHY? WHAT DID I DO WRONG?
