Should i divorce my husband for texting his X's?

We have been married 1year and dating 2yrs. We met in the military and hes from georgia and im from California. We are living in California. Even to this day he is texing his x's and uses facebook to communicate with them and even meets them when he goes to Georgia and does not tell me and always makes up lies when i catch him, He admited that last of fourth of july one of his x's got naked for him when he went to see her and he still flirts with her and his other ex's he says its not flirting and that hes just being a friend and boosting there confidence, but i dont think saying about private parts like and just other stuff that i dont even know because he lies about it is ok. He is black and im hispanic i dont know if that anything to do with it because he says thats how they talk in atlanta GA i am so tired of this and dont know if i should continue being hurt in this marriage or divorce and continue college and my life,
