I had a brief relationship with a man 18 years older than me while living out of state. He led me to believe he was only 10 years older, or else I wouldn't have dated him. Despite using precautions, I became pregnant. I moved back home without ever telling him because I was so upset because he lied about his age and think he is too old for me. He seems like a decent person and has never been married and has no other children. He always told me he wants children someday.
I am now in a relationship with a wonderful man who loves me and my child very much. I do not need financial help from the biological dad. My child is 11 months old. If I tell the dad I don't want to wait too long. I'm not sure to tell him, since we probably won't have a relationship.

What should I do?
