My guess is that this site is taking your attention away from her being miserable.. misery wants company and probably influence too… she might just want to disagree with whatever you say to argue and win, but this site has it’s hooks into you and you’re debating with her less in your silent sense of housing-decision confidence.
I believe some problems are almost unfixable and become especially hard when nostalgia is sacrificed in the solution.
Since you have 500k sitting around.. go buy a cabin on Palomar Mountain, they’re really cheap and the supply isn’t that high anyways.. or you can go to some other remote semi-vacation/relaxation area.. maybe an inexpensive retreat like this will help repair things..
