I keep in-law relationship as a business one, minimal physical contact as possible, and we normally meet only on special occasions & holidays & birthdays. Mil has done some devastating action to my first pregnancy right after we lost the baby ( my parents will never forgive what mil has done to me, their only & beloved daughter), and she treats unfairly to my toddler grandson (she loves her the other toddler granddaughter (dh's older brother's daughter) that she helps out as a nanny since day one). I mean life is never fair, dh's older brother & family is her favorite. It causes both me & dh pain with tears , so better keep it a harmony by keeping a certain distance.
