If you have to stop, stop. If you have to talk it over with your WW, have her comfort you, or have her leave, do so. Do what you need to do.
I've had to ask my FWH to do all of the above at times, especially in the early months. I also got very selfish at times and pretty much expected him to do all of the work. I've used the stop sign and frankly, I've also mentally done a "oh yeah? Watch THIS you *$(#*&!"
You may have to try several things until you come up with something that helps, however one thing that does help is that four letter word, time.
