I have a question about 15 and 19.

Isn't 15 kind of faking it actually? And if you come across as something is wrong and then you say "nothing", do you really expect they will believe that? They are going to think your looking like pouting and then saying "nothing" is totally a game to get them to really probe you about what is wrong.

As for 19, if someone were to want to improve themselves in any way, it might be interpreted as competing with the OP. But then what do you do if you know that is an area that needs improving in your relationship and you sincerely want to improve it? Why is that fake just because the OP makes you realize it or makes you realize you can solve it?

I think there are a lot of good points here but where do you draw the line between being the NEW and BETTER you that is supposed to be attractive to your spouse and playing games or suppressing yourself in ways that result in you not being new and better?
