I have been in a long term relatioship with a man who I thought was perfect. I thought our relationship was perfect. 10 years is a long time. We do not live together but alternate weekends at each other's house. We go away every year on beautiful vacations etc. Now here is what happened...I have never met his daughter and the reason that was given to me is because the mother does not want any other women around her. So I respected that. After calling him and talking to the daughter, she told me that her father is still with her mother and that there is no way I could be his girlfriend. She said my dad lives with us. My heart fell right to my stomach. I thought I was going to pass out. I confronted him and asked him what is going on? He denied everything his daughter said and told me every child wants their parents together and she is making it all up. Now the problem is I do not believe him or trust him anymore. Should I just let it go and believe him when he tells me that his daughter is a liar? Or should I get rid of him?
