Boyfriend troubles need help asap

my boyfriend checks out and flirts with other girls in out class I caught him and he admitted it to me. but we said that no matter what we want each other not them. but I still get a lil hurt,mad and jealous. I try 2 keep my cool but I try not 2 be this over jealous girlfriend. how am I suppose to keep my cool?!!???!??!?!?! help!

I think the age of both of you is mainly for flirting around in the class. Do not worry, but rather try to do the same. You do need that experiences that you may gain by making male friends.

Do not be jealous, but start to socialize with other young people like he does.
