As far as traveling with someone I won't live with, I have taken several vacations with several people (relatives & not) over my adult lifetime that I wouldn't want to live with either, but they are fun- in a relaxing atmosphere of a cabin at the lake or touring a city, or a road trip- depending on who it is.
I get that, I do it often. That's about the only way I can afford to travel in my current sitch is if I 'trailer pool' with someone!
The real question though was why you would consider traveling and vacationing with your H when you won't live with him. You answered that when you said it was a promise made long ago to your son. That's cool.
If H said to you, Hey Bridge wanna go on a cruise with me? (or whatever) - would you go?
Congrats on the art of plumbing!!
Live your life while you are still living. Riding the trail less traveled.
