okay so me & my boyfriend have been dating for almost 10 months. & last month i found out he was talking to one of his exes, but it was a long distance relationship from like in 2011, she lives in arizona & he lives in NYC.. he was talking to her about their past "dating" experience even though they were long distance.. but i SPECIFICALLY told him not to talk to her but he did anyways. face timing, texting, & saying some stuff you shouldn't say to another female while in a relationship. I NEED advice from you guys. what should i do?
