they passed a law in 2019 that you don’t need a new TM30 if you return to the same home if if you left the country. Immigration offices varied if following this. Now Bangkok has connected the TM30 and 90 day reporting systems, so you need a new TM30 every time you either 1)stay at a hotel that does a TM30 or 2)leave Thailand and return

U.S. government is absolutely hostile to expats, tourists, and (legal) immigrants. Try visiting a US Embassy or applying for a tourist or marriage visa for your SO, or requesting citizen services.
