How to understand that a man wants a family?

He becomes more caring, shows attention, worries about your health and well-being. He spends a lot of time with you. He is ready to give you a space where you can arrange your necessary women's things. He tries to do everything to make your stay in his house comfortable. You are a part of his life, which means there is no need to hide you. He wants to show you to others as his partner.
