i have been with my significant other since 2000. I have a son by him that is 6 and a daughter that is not his who just turned 11. We have had a lot of ups and downs and in 2006 we got custody of his three children from a prior relationship. he also has another child by another woman. Before they came to live with us we was having another down time and was even talking about leaving each other. Once they came the focus changed because his childen have mental health issues. He also was diagnosed with congestive heart failure. Just recently his condition turned for the worse and he now needs a heart transplant. In this past fall, I was sitting on my front step doing my daughter hair when his childs mother came to talk to me. I told her she needed to talk to him because he is the father. He was walking up as we were talking. During the conversation that they was having it was revealed that he signed an acknowledgement of paternity for her three year old daughter. After hearing that I went in the house fuming. My son was supposed to be his last and he is six. When he returned in the house after now arguing with her, I was ready to end the relationship rihgt there. I stayed because of my children and his children and the fact that his medical condition will be taking him away from the children at some point. He now wnats to get married. I have been putting it off because I can't let go of the past. I feel as though I have been short changed during these past eight years. I will be thirty soon and that also take play. Any thoughts???? suggestions???? We have had some counseling.
