When dating a single father, keep the following in mind:
1. His child comes first and things will not go as planned.
2. Your relationship may start as a secret as he wants to make sure things are going well before Introducing you to his children.
3. His ex is here to stay and it’s important to respect that she’s the mother of his child.
4. He’s ready for a serious commitment. He knows what he wants and where he wants to be.
5. Be independent. When he’s spending alone time with his child, you should be out with friends or enjoying some me time.
