, then honestly the best 'fit' for a visa for you would be to go to a thai consulate and get a 90 day single entry Non-O visa based on marriage. That would stamp you in for 90 days and you could extend that by 60 more days at the immigration office for 1900baht too.
Seeing as you're only here 100days a year, it doesn't make sense to get a year long visa that you'll use only once. Just get a 90 day single entry visa from a thai consulate in a nearby country like Vientiane, Savannakhet, Ho Chi Minh City or Seoul.
The consulates I mentioned do NOT require proof of funds to issue that visa.
