Left me mid sex??!

need advice or thoughts. My bf came over and we talked random stuff and unfortunately he started giving me oral and I started enjoying it and all good. Next his phone rings and his dad asks to pick him up and he says yes and lick my vaggie one more time and says OK I gotta leave!!!!

Like what??? He just left me like that within 2 mins he was gone.. and I'm horny 2 days in a row and we couldn't do much stuff because we live with our families and now he starts doing something just to leave like that. He gave me oral for maybe 5mins.

This is very weird to me because he wasn't like this before, he used to go downtown until I came.. I need some thoughts. I feel like we are getting less and less intimate with each other.. I felt like crying but I hold it in..
