H is contacting PW and lying to you about it. What part of that is OK? You set the boundaries of how you will be treated in your M.
"I have decided to focus more on GALing again and less on scheduling with/around H.. not sure what more I need to do, though. Thoughts are welcome as always!"
This seems like a good idea. Perhaps you can go out with your singles group again. I'm not sure why you should be more into the R than H is at this point, it isn't particularly good for you or the M.
