Need Advice. I have 2 children: boy-12 and girl-13. My live in boyfriend also has a 12 yr old son. The boys fight constantly! It's even getting physical. We can't even go out anywhere, because they misbehave and it's very embarrassing. The 2 of them pretty much set the mood-if they're miserable, we're all miserable. The other 3 of us get along fine with each other, and the boys. Any suggestions???
