I constantly feel like I am in the middle of my teen son and my fiancee. Any advice on how to cope? My fiancee is wonderful and we have a daughter together. My son is wonderful but he is 14 and rebelling. His father doesn't discipline him at all, I feel I am firm but fair and a bit light on punishmment but not lazy. My fiancee is old school, set in his ways and too strict in my opinon. We are in a constant battle.
