Let me set the background on this piece of wisdom.
When Frank and I were seriously dating (or maybe even engaged), this is what my mother told me...
"Whenever you and Frank have a fight, DON'T tell me the details because you will forgive him and I will have a harder time forgiving him."
At the time, that seemed very strange to me. Now that I have children of my own it makes perfect sense (the quickest way to hurt me is to hurt my children). I have heard several women tell me how true that piece of advice is (from their own experience) and how they wished they had that very same advice years ago.
I've told Frank on several ocassions what my mother told me. I tell him (often) that when the time comes he will have to remind me of that piece of advice. I pray to God that I will be strong enough to tell my children the same thing.
It will be so hard to cut those apron strings, but that is exactly what we are supposed to do [Eph. 5:31 "For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh."].
I've heard it said that "A mother's job is to work herself out of a job." How true that is.
