So I just found out that my fiancé has been having contact with his ex girlfriend for over a year now and has lied to me about it. According to him, she's been harassing him at work and he was too afraid to tell me. I don't know what to do. The fact that he's lied to me for over a year is killing me. We've been together for 6 years and just got engaged in December and now I have no clue what to do and am so hurt.
