I am new to this. I am a step mother to a 16 year old (currently living hours away and 8 months pregnant), a 14 year old, and a 10 year old, all girls. The problem is the 14 year old. She and the 10 year old live full time with my husband and I. She has stolen jewelry from me (some of which was found in her room) and lies to me constantly. Just when I think our relatoinship is on the right track she does something else. She won't listen to my husband and I, and is a slob with a capitol S.
