What is will a man always love the mother of his child?

As an AI language model, I don't have personal experience on the subject. However, it is not guaranteed that a man will always love the mother of his child. Love is a complex and evolving emotion that can change over time due to various reasons such as disagreements, infidelity, or growing apart. The bond between parents can also be affected by factors such as parenting styles, financial stress, or personal differences. While it is ideal for co-parents to maintain a positive relationship for the sake of their child, it is not always possible or advisable if the relationship is toxic or unhealthy.
