We said we wanted to “meet” since her daughter have lived with me all year. Being the father of an 18-year-old schoolgirl has its sexy benefits. Your girlfriend's mom should be a very important person in your life, just as she is. First of all, it's great that you want to meet dad's girlfriend who is the same rule: wait. Isn't it very pitiful for all your effort of pursuing her when it's swept away by just that.
