I agree with Lady D. I am lucky to have a wonderful mother-in-law. However, she will NEVER, EVER be like my mother. Never. But she isn't a bad person. She just isn't my mom. So I understand that too.

Something else to think about. New doesn't mean better. New simply means different. Change. (Change is very hard for me.)

When my grandmother died, it was hard on my mother. Years later my grandfather remarried. My mom never called this woman "Mom" but she came to care for her. She made my grandfather happy, and that was what was really important to my mother.

No one can ever replace your mom, but it doesn't sound like anyone is trying to. They're simply comparing. Comparisons can hurt, too. I know it is hard, but life must go on. Grieve your mother for as long as you need, but don't stop living yourself. That is not what she would have wanted.

Good luck.
