My daughter's father and another male and I were friends all through high school. My child's father and I got together senior year and our friend went to the Navy. My daughter's father passed away 5 years ago, at a very young age, from a massive anerusym to the brain. The friend came home to what I thought would be a casual visit to check on my daughter and I, but it turned out he came to discuss his interest in me. No one in our family knows we (3) were best friends in high school but us. Do you think it would be wrong for me to pursue this as a relationship?
