it is very sad that your child did not get mothers and fathers both affection. atleast you should have communicated to him your feeling. you could have been near to him eventhough physically miles away. now when he needs a father. you want to create hatred towards mother and take his love. this does not happen practically when you are married and staying away without any communication. Your child will start hating you and will never come to you no matter how much money you spend on him..
your love for him is true but unless you do not express he will not understand.
