How do I handle moving in with a single dad?

I think he needs to have a talk with just her first. He can tell her how special you are and that you will be moving in. He needs to let her know this is about grownups caring and wanting to share their lives together. He first need to make sure that his child knows that he loves her and she is the most important thing in his life and the love he has for you is a different love. Children get insecure when there is a divorce. You two have dated for two years and want to move in together. Seems like you would get married and then move in. The man in this relationship I respect that he is not sleeping with you in front of her. This shows his Morals. He doesn't need to explain this to his little girl. good Luck
