Why isn’t he proposing?

I have been in a relationship with this guy for three years. Our love has blossomed and we are happy. He has, however, not proposed to me despite the fact that he has been to my home several times and my family members like him. I think he is taking time to propose to me because I have a daughter from a previous relationship. I’m sure he wants to marry me, but he is scared because of my daughter. We are both ready for marriage, but I need your advice on what I can do to get him to marry me. He could be thinking twice about our relationship and I don’t want him to leave me.
