What is love? I had an affair because I didn’t get the affection I needed from my wife. My daughter-in-law isolates our grandchildren from us; how do we break through her control? Do you recommend I get a family negotiator? One son copied my other son’s business to the point of plagiarizing him and stealing his ideas. I am a good father but have failed at four marriages. My fiancé says I’m angry; what can I do?
