Speaking from experience, I have the son and not the daughter. My son got a girl pregnant at a young age, and I also was not happy. The girls mother said to me "Hope you have a place for her." WOW. That's my grandbaby dang skippy I do. My son did not marry her but she is a big part of our lives and I would not trade one moment of that time. Each child is put on this earth for a reason, you and I may never no why but just love your daughter and support her and your grandbaby.
