I have friends that have married in the past few years and yes they paid. From what I understand the amount is based on the education of the girl and the level of job she has. My friend married a girl with a college degree and working as a flight attendant, he paid $30,000 in gold. He got nothing back. The hard part was all the ceremony. You can not embarrass the family in front of friends..
You should be able to get a job as an English teacher, Thailand has a push to hire a number of teachers now. Also many people get a Volunteer Visa or an education visa to learn Thai.
If you can wait unit August, EVA will again (maybe) allow transit flights and you can fly to CNX via Taipei. Russian airspace being closed is causing a disruption in flight options and prices, I flew back to USA in early May via DOHA and the flights were full and the airport was jammed. Prices are about 50% higher than pre covid, maybe some moderation late summer but likely to remain high for a long time
