I think most of the trouble is due to her age. My 2 year old has intense mood swings too, but my husband and I are still together. Part of it could definitely be from the divorce. It sounds like you have given her a very stable and loving atmosphere at home. If her father is not caring for her as well as he should be you should talk with him. Reconsider your guys' custody agreement maybe if he's not willing to tow the line. I think she'll grow out of most of it. My oldest child became a whole new person at about 4 1/2 yrs old. Good luck.
