While I'm not married, I've been with same lady 15 yrs, have a kid. 200K baht is a small amount of money. I paid that much almost for the house party we had. A live band on stage in the rice paddy. A truly epic affair. Lasted 3 days, one to set up, one for party and one for clean up.
If resources are limited then why even think of marriage. If paying a bit of money is a challenge then stay single and enjoy the bar ladies.
