Well, doing what I wanted didn't get me the result I wanted. . . . Typically, when I assert a boundry, she gets angry. I am kinda beating myself up now. Things were going well and now she is pissed.
Wonderful,
You're right to be moving away from doing things based on whether or not they will make your wife angry, and placating her, but you're NOT supposed to be doing them based on "what I wanted." You are to begin doing them based on "What is THE RIGHT THING TO DO in this situation? What is the thing that God Himself would have me do, if He were standing in front of me?"
A common mistake for new DB'ers is that they swing wildly from old pleasing/placating/'Mr. Nice Guy' behaviors, into selfish, irresponsible ones. Yes, begin to learn to look out for your own interests, but do so from the "Right Thing to Do" perspective.
