It is sad when people you love treat you if we are less than they are, especially family like a Mother, daughter in law, any relative for that matter, it hurts much more. I has happen to me, many times over right after I thought I had given them my best. There is a scripture in the Bible that deals with it, Proverbs 17:13 (BBE) If anyone gives back evil for good, evil will never go away from his house. Sometimes the best thing to do is to depart from them no because of ego, but because of self respect.
