I was married in 1999 to a man who had several girlfriends on the side that I did not know about before marrying him. We were only living together for 6 months, the entire time of which he was cheating on me. When I found out I confronted him and he moved out and I have not seen or heard from him in 10 years. A woman called me a few years ago and asked me if I knew him and I told her yes. She then told me that she had just gotten married to him and I told her that I was still married to him. She then hung up on me and I have not heard from her since.
My question is: Because of the situation, would I be eligible for an annulment or would I have to get a divorce from him?
