My theory is the daulter-in-laws favor men and like to be adored by men. They see other women as a threat. I am experiencing this with both of my sons. The daughter-in-laws have no women friends. One of them doesn't talk to her own mother at all. The other one favors her dad and has said her own mother has "problems". Both of the daughter-in-laws were married before and say horrible things about their previous mother-in-laws. This isn't about us...this is about young women that have been raised to think that it is all about them. Both of my daughter-in-laws "love bomb" my sons. My sons dont' get it. One of my sons did ask me why his wife does that...but he doesn't really want to hear the answer. Look up Dr. Joshua Coleman and listen to his "Cult of One" podcasts on YouTube. It helps to understand, but it doesn't help with the pain.
