Help, guy troubles! What should i do?

okay so it sounds like ur bf thinks u betrayed his trust by talking about u guys with his friend and i am sure is friend told other people so of course he is going to act like a dumb male. but i would say if the other friend is really nice to you and treats u better then ur current bf then i would say continue to see if the other friend likes you then if he does break up with ur bf and go out with the other one. u don't want to be in a relationship were he treats u like dirt around friends trust me :( so i would say his friend if u can find out if he likes u and if not still break up with ur bf or explain to him be like look ur a jerk to me around your friends change or we are done good luck :)
