There is a good chance of an incest child being mentally retarded...very selfish to take a risk of creating a child that might have a lifetime of suffering like that.
Have to say...if the woman had known her dad more as a dad while young she might have listened to those screams more. He was a stranger that she longed to know...........thanks to the ex.
Can tell you one thing......if the relationship ever goes south....it gonna be nasty.
just two cents
