oh and one more thing...about 5 years ago his ex was in town visiting his sister and the ex went to my husband's work during lunch. I guess he felt guilty like two months after this incident happened and he mentioned to me. I told him I did not feel comfortable that this woman was back in his life. he argued that he really likes her as a friend and that he would not mind to have a friendly relationship with her. I told him I would not want him to have her as a friend. About a week later his sister called me and said that this girl and her were friends for a long time before I came in the picture and that she was going to continue to be friends and hang out together with her even if I did not like it. I told her that I had never said that she could not hang out with her and that I was only referring to my husband and I when I said I was not comfortable being friends with the ex. (There were several minor incidents with included the ex and his sister before and after this incident).
