How Do You Approach on the Front End of a Relationship?

i've got a 21 year old daughter who's unmarried, and a son who's on a mission right now. He's been in a relationship for the last couple of years with this girl fan. I think one of the things i have said to my kids is that, you know, the most important thing is to be capable, within yourself, of repentance. When you will not self confront, won't look at yourself, demand that the other person feed you the picture of yourself that you want, it really undermines the ability for that process to happen," he says.
