How does a father stop being a father after a dna test what difference does it make if the child is yours or not

Being a father is not making a sperm donation. That's just biology. Its about being there to support the mum and the child from the moment conception happens and that continues all the way through that child's life not stopping at age 18. They protect and provide financially and emotionally, help create a safe space, give discipline that teaches but without breaking a child's spirit. Great dads are under valued I think. 😊
