I have a three year old SD whom I cannot, no matter how much I TRY, get on with. She lives with her mother on a permanent basis, but comes to us for two weeks at a time. My anger towards this child is terrible and when she is here, my fiancé turns into a totally different person and its almost as if I do not exist! I have researched every basis possible to try and figure out why I feel this way and what I can do to change it, but to no avail!
