Couple things, DM...

First... so... what is your answer to him getting you a car?

Second... let's say your H was just a friend... how would you support him in working through his... time of "confusion"?

Third... multi part, maybe... how would moving out be helpful for you? for your M? Why Vegas? (would that be YOU running away? how far do you want to run?)... and perhaps more to the point here... what IS your goal? Do you want to R? Or are you done and just want to move on?

Oh... as far as him missing you...

Think about this... what's the "best part" that he KNOWS... that YOU know... RIGHT NOW... about you... that he really would miss...? ie. Will he miss something that he originally ran away from, or will he miss something freakin' amazing, that he didn't have with you, prior to your sitch?

You are correct that everyone has something to offer. Be careful of the "grass is greener" syndrome... as your H... ALSO... has the potential to offer something... at least maybe... or maybe not...
