I travel to Thailand about 3 times per year to stay with my Thai fiancee. I usually rely on the Visa Exempt Stamp on arrival at Suvarnabhumi. I have never done a visa run or entered at a land border. Recently on arrival the immigration officer questioned me about why I visit Thailand so often. I explained that I am in a relationship with a Thai woman, I am retired and I don't do any work there etc. He could see that I don't overstay the 30 days and he asked me why I didn't get a visa in future. I explained that I don't want a business or retirement visa etc. and by 30 days I have had enough of Thailand and I'm keen to get back home for a few months. My question is would there be a possibility of being refused entry in the future if I continue to rely on the Visa Exempt Stamp on arrival? Thank you for any advice or suggestions.
