What to do in this situation?

If she's a full-fledged union teacher in a public school she'd be walking away from great benefits, a pension and any seniority she's managed to build. It's not that easy to get back into a plum position like that. So don't minimize the sacrifices she'd be making. The default position on questions like this is that if you're not both in agreement you don't make the move. Unless she expressed to you during your dating years the desire to live abroad it's not like she's springing some surprise on you...you're the one springing the surprise on her. For motivated people who've worked hard to secure a career not working for 4-5 years would be abject hell.

So you won't miss your family and think she should be the same as you? You are not complaining because you'd be getting something you want, but what about her? Did you marry her because you thought she was identical to you? Or because she is the individual with her own needs and wants?

This job means she won't have meaningful employment for 4 - 5 years and it may be hard for her to find something if and when you return, if SHE wants to? Did you consider that? Maybe her work gives her a sense of satisfaction, just like yours does for you. Why is yours so much more important?

Are you thinking about kids? Does this mean delaying having a family for that time? How old are each of you?Is the delay reasonable? Or do you not want kids? What about her?

OR will you two be far from adult children?

Or perhaps having the children born overseas? How will that affect them if or when you want to go home? Adjustments, etc.

Do you speak the language? Does she? How much of an adjustment will it be - different culture, different language, arranging new accommodation, different lifestyle, far from home, etc.

Do you propose to return home on holidays? How often?

Lots of questions. Do you have the answers? And would they be the same as hers?

I’d tell her you’re going there with or without her. Stupid teacher with her stupid little community obsessed teaching job making $30k a year thinking she’s important. Fuc*k that. She’s selfish. She only cares about “having fun” and “being fulfilled”... meanwhile you’re slaving at a hard job. She should let you go there and earn a high pay for 4-5 years so y’all can buy a couple rental properties with the money to make passive income, or retire afterwards. Seriously. I’d tell her you’re going either way and your paycheck won’t be going home to her. You’ll be getting a divorce if she doesn’t come with you

Lmao if it's Brazil or Thailand she's definitely gonna have issues.

It's not the money she's worried about.
