I have just learned that my fiancé of two years has been telling his ex-wife of 6 years that he misses her.. On top of that crying will doing so. I am so damn mad I can not even see straight. I have left him simply because there is no place in my life for that type of behavior. He has two children with this woman, none with me. I have a child from a previous relationship. My sons father is deceased. My fiancé and I have been together for 5 years. My son was 1 when we got together, so he is the only father that he knows. That is the difficult part. I normally have no problem making my own decisions, but this one has me cornered. Any advise?
