Wow! Your story is so relatable to mine. I am new here also and have yet to post my story (about to) but I also have a military spouse who a year ago wanted to end things, we got back to normal, and now right back to wanting out of the relationship. No affairs involved, just the ILYBNILWY frustration. Sorry I cannot offer much as I'm pretty much in your same boat, but know there are others who are feeling the same pain.
