Did I overreact? (Virgo/Capricorn relationship)?

not really sure how he will react, no one can predict the future, But I can say that if he love and care about you as much as he leads you on to believe then he will come back and apologize and hopefully work things out unless his friends mean more to him. I also suggest that when you are in a relationship you and your boyfriend have friends that are in relationships to because people that are in the same situations tend to understand more, If there boy has a girl then he will understand if he has to go to hang with you or most of the time you all will end up hanging out together. Good luck.
