Tipper, you are very right when you state you are the only one that can decide when or if you quit. Just be sure you are staying M for the right reasons.
I hung on to my 1st M because I simply did not want to be labeled a divorced person for the rest of my life. Finally the last straw was thrown at me and I filed.
I hung on to my 2nd (and current) M because I never stopped loving my H.
Hope you have a great camping trip! Stay safe!
