I know its wrong to ask... what does this trip mean? Is it business or personal? ...that is pressure and controlling. He would feel pressured by this questioning & fluff it off and say "I just thought it would be nice to get away, have fun"
But, how will I know HIS truth... when he's being just too casual??
Is his "casual" his truth? THATS IT? (he has mentioned many times about wanting to "see" where it goes... no commitment).... GRRRR
Well, yeah -- of course. MM you have a full 20 YEARS of data here from which to draw. If you want to know what he wants, just look at what you two had before. That's your "at best" scenario of what it is that he wants -- that he wants to get back to that again.
"At worst" it's what Ken and a couple of others have posted -- xBF really is trying to dump you, but let you down easy, out of some combination of basic human compassion and his looking out for his own business interests.
Only you can decide if you can live with that "at best" scenario, but I think it's clear after 20 years -- and after the past two years of you TRYING to pin him down for more -- that this man is incapable of that.
