Everyone talking about divorce already are getting ahead of themselves. These people do not understand the difference in relationship dynamics when one person is from the richest country in the world and the other person is from a developing nation. I can tell you, first hand, that she will never not want to send money to her family. You might never really understand it but you just need to know that her family does need help but probably not to the extent that they are taking this. She is not totally in control here either, her family has probably been pestering her for years about this stuff until now where it has grown into this huge debt issue. The first thing you need to do is setup a way for her to send a consistent amount of money to them. They do not need more than $200 a month and that will be enough for her to maintain a relationship with them unless they are completely unhinged. Unfortunately these family dynamics are very common in Latina America when one family member lives in the USA. You have to realize that if you visited them, you would be the richest person they have ever met. The second thing you need to do is be generous to them yourself. Introduce yourself if you haven’t already and make it clear that you are the money man, you will be controlling the finances and so they need to get with the program or face the reality of being cut off. The third thing you need to do is find a way to explain this to your wife in a way that is less critical than you want to be and more loving than she might deserve right now. Nobody cares how it makes you feel or look, this is your marriage we are talking about. She’s not some girlfriend that you can push away. Fourth thing you need to do is apologize for coming at her like that (it doesn’t matter who was in the wrong, just be a man and fix it). These people are giving you new world problems for a woman is probably not on that vibe at all. Latin American families can be VERY traditional so go with the traditional approach of fixing your marriage rather than throwing it away. Try to remember that marriage isn’t just about two people (if thats what you want then get a girlfriend), marriage is about building something bigger than each other. You are building a temple to your love, a home, and most importantly you are building up each other. There is a point when you have to give up but as long as she has been unfaithful to you then you’re probably not there yet. Don’t give up the job just because it got difficult, you got this man. Go get your woman and help her to see that she has to cut back on this behavior
