DaMoshe > He did not see a healthy relationship between his parents,
R Pliskin addresses this in his book “Marriage” (highly recommend).
You ask such a person – did you ever witness a healthy family, but only a couple of days a year being a guest somewhere, majority of my memories are of unhealthy one.
Then, a solution: continuously play in your mind positive experiences you had, and then majority of your memories would be of healthy events and you can apply them to your family life.
