Hmmm, the fact that you've been together for 2 years - yet he didn't ask you to go with him feels odd to me, especially when you mentioned that you've "talked of marriage". Also, when you said you both wanted to get married, but wanted to wait until you were "financially stable" - I didn't get that. What does love
really have to do with money or being financially stable? I can understand wanting to wait for stability when it comes to kids. But if you have REAL, lasting, deep, love here - then why wouldn't you both want to BE in this journey together already? Whether it was to be here, Bolivia, or wherever? And, no matter whether the finances were just right yet or not?
I guess my point is, I'm sort of wondering if you both really want this or not. Because, what I see from the outside is - the two of you noticing or creating a lot of barriers instead busting through all of them so that you can be together. But, that's *just* from the outside - and could be totally wrong!!!
Alllllll that said, if this is real and meant to be - and you love each other - it won't matter if you're here or there, it will work out for you two. It may be difficult and trying, but it will.
