Ive been talking to this guy for 2 DAYS, why did he.......?

Send a pic of me to his mom andat first he yelled at me ysterday saying Im shaddy and all I want is when I was making a joke? Were both looking for commitment although Im seventeen and he's nineteen. He doesn't do any drugs which js good but I like to drink ONCE IN AWHILE and he kind of said how that's unattractive but he drinks? He says he gets buzzed after one drink? Doesn't want which I know is a good thing when looking for a relationship but if Im dating him for awhile (months) and we are really committed I probably would want but he turned me off when he said his ex made fun of him cause he only lasted 30 secs ....how could you *** that quick?! Id want to make love for hours. What's up w him!?
