I just started this wonderful guy that has a 3 year old doughter that lives with him.She is nice and loves me, but for some reasons she is like a little brat. My boyfriend and her fights all the time.I feel bad because he tells her to do something and she don't listen and starts crying for no reason.Her mother left when she was one and she don't know who she is. I really want them to get along and he tries to talk to her sweet she just don't understand.. I need help, I feel bad when he yells at her or brings her to her room.
