I've come to this site to reach out to WHOEVER can give me some advise on being a new stepmother. I am 27 and have been in a serious live in relationship with my boyfriend. He has three children full time age; 14, 13, and 11. I also have my own daughter from a previous relationship who is 4.5. I feel like a totally awful person for not liking the youngest of his children. She is the 11 year old girl and if I'm being completely honest I almost despise her. A little background first, their mother is an on and off alcoholic/drug addict.
