You are going to get many opinions on what to do. The key is to understand all the choices you have, and then make the best choice based on what has worked for others. I strongly recommend following PDT guidance. I have seen people follow his advise and bust their D. I have not seen anyone bust their D when they do not follow his guidance.
With the in-laws, I would like to strongly suggest that you DB them also. They are extensions of your W.
Here are some of my mantras:
Always do my best. Do not take anything personally. Face my fear: Do not let fear control me. Do the right thing. Do not make assumptions. Be impeccable with my word. What is best for my kids is best for me. Stay in the present. The past is history,the future a mystery. Respond rather than react. Listen rather than speak. Change me rather than others.
