I've Been Divorced for 15 Years and I'm About to Remarry

Catherine, what is normal? I've been split from my ex-husband for five years and am happily about to remarry myself. However, his mother seems to not be over the fact that we're divorced. She feels it brings shame upon the family. We were very close when she was her daughter-in-law but she became more controlling and difficult during the 15 years we were related. My daughter tells me she rolls her eyes or changes the subject whenever I am mentioned. What should I do? Should I confront her for being fake? Or just be the bigger person? Ignore it.
