Do you realize you’re the first male relationship she has? Do you know the patterns that are emerging and what she is being taught in regards to how she should interact with a man. She sees that she should wait on a man and be accepting of anything that comes her way from him. I would go as far as saying these actions will be used in all of her relationships including friendships. Do you want your daughters hanging around, waiting for men and accepting any little tidbit they offer?
Girls need to know they are a priority in their father's life. They need to know what it is like to have the promises kept, to have the door opened for them, to be treated like ladies. If you as their father; the most important male in their life does not teach them, who then will?
