I didn't come for love but did stay for love, it's been 6 years.
When we first started dating he was firm in the "I could never leave my family camp" as if to say "if you want to be with me, it's here" warning, and me with my rose colored glasses said "why would I EVER want to leave here?!"
In the end he changed, he fell in love with me and realized it wouldn't be fair at all to say I'm the only one to have to sacrifice, especially since I'm the only child and in reality he has three other siblings who could care for his parents later in life, and mine will be alone (just to name one of the many obvious factors that make it hard to be far from home). Both of you have to make compromises, our lives make more sense here now, and in the future we want to end up in the US but with lots of time spent in Argentina out of each year. Make sure you'll be ok with never living back in your home country if you really think she'll never bend on that, because you don't want to resent her down the road.
Workwise: See what remote work you can find. I juggle 4 remote/work from home jobs now, 1 full time, 3 other odd jobs, and all pay in USD, all allow flexibility for travel. Upwork.com is a good source. English teaching won't earn you a great income you want to live on long term (from what I hear, to be honest I've never done it)
