I've read many posts here about people who cajole their spouse into moving long distances because they hate their current location... only to find out they're miserable in their new location because they never dealt with their underlying issues.

I did this as a single person. Picked up and moved to a new continent thinking that a change of scenery and a new job would be the solution to my problems. And I was happier...for about three months. Then I was back to feeling listless and unfulfilled like before because moving did nothing to address my underlying issues which had nothing to do with my location or job. Ultimately it took a long stretch in therapy and antidepressants to get me back to a good place.
