It’s clear that your understanding of your relationship with her is different from her understanding of her relationship with you. Love is secondary to a lot of issan village girls. On one hand deceptive and tricky, on the other heavily influenced and coerced by her surrounding. In her mind she’s fulfilling her duties to you by meeting your basic needs. If she’s chosen a path that doesn’t accord with you, being in her “natural” environment will make your task of “sorting the issue” very difficult.
Try this: tell her you’ve been offered a work opportunity to move to a far away location for a year. Make the assumption that as your partner she’ll be going too. Use “we” a few times. “We’ll have to find a place in such and such location”. If her reaction is that she’s not willing to go, but it’s ok for you to go then you know you’re just her ATM that she needs to provide some maintenance for from time to time. You can then decide whether this is what you want from life or not. Remember their definition of love is not necessarily same as yours.
