I have a three year old daughter and a six year old step daughter. I have been with in a relationship for five years and I feel it is starting to fall apart. my three year old isn't an angel but she does listen. my stepdaughter lives with her maternal grandmother. and we see her two times a month. right at the moment she is with her mother for the summer. Her mother has hated me since day one, wants to beat me up so badly, and tells her daughter to be mean to me. when she comes over she is demanding, bossy, hits, and throws things at me. she bullys my three year old. I've told my boyfriend that she does this and he doesn't like to discipline her. putting her in time out is a joke. and when he does discipline her he gets angry at me. I also get tired of the fact that every time she comes over she has head lice. I really do love him but I don't know how much more I can take. if you have advice please help.
