Thanks, but this isn't about who has the best "lines" or pithy retorts. It's about the proper and healthiest overall ATTITUDE, and what kinds of CORE BELIEFS you need to decide that you have . . . and then learning how to project those and, when necessary, enforce them.
Your CORE BELIEFS come first, and then your STRATEGY should flow from that, and then finally your TACTICS flow from your strategy. I don't think you've ever really figured out the first part of this, and if you ever do, I think you're obviously a really bright and personable guy -- I really think the strategy, tactics and "lines" will flow naturally from you.
You need to LOSE THE FEAR, and figure out what it is that really IS non-negotiable in your life, and in your marriage.
