I don't feel anything about my newborn son.
Do you have any idea why you don't feel anything about him?
I thought I was a family man and must be a father to my son, but I can't feel anything for the kid.
When you first have a child, you are under a lot of stress and this can affect your emotions. While being numb to your child can be okay at first, you should start to feel emotions towards your newborn as you can for him. If empty feelings persist, it might be a sign of having a psychological disorder and scheduling a session with a mental health professional is recommended in that case.
I just don't get it. I am a responsible man with a family, but I only want to do my job and make a paycheck to provide. I feel nothing else.
Your feelings of emptiness towards your kid need to be dealt with here. It isn't enough just to earn a paycheck for your family. You need to seek professional help to get down to the bottom of your real feelings so that one day you can connect with your kid.
