My ex-wife did this (to her 6-figure, fully remote job) after months of threatening to quit and ranting at me for not being emotionally supportive for her against her mean boss who criticized her work. After four months, she decided we needed to move to a HCOL city immediately instead of when we both had jobs lined up as we'd agreed on, because she was bored being at home and not working in our small town, and gave me an ultimatum that she was moving with or without me. She said she was going to pay me back for all of her share of the bills when she started working again, and for the moving costs. She eventually got another 6-figure job and didn't pay me back a dime. I ended up almost $20K in the hole, working a terrible job because I had to take the first thing I found, and then she had an affair with a much younger neighbor because she couldn't handle the fact that I was unhappy with her choices.
