Tough question,
should you show the love when they are in the midst of an affair?

In essense, that's what the affairee did, show the love they wanted. The difficulty is it turns into pursuit, groveling, and low self-esteem. PMA, FAITH, PATIENCE.

I'm visiting my parents for a few days. My sister called and wished me good luck. How's that? We are the classic example of don't get the family involved. Don't do it!
