First off -- this doesn't concern my marriage. While I may obsess about killing large swaths of the U.S. population, I am a tender family man, and so far have been fortunate in love, much like Joseph Stalin.
However, in my observations of acquaintances, I have noticed very different patterns between Anglo and Latina wives. Keep in mind that YMMV.
First of all Latina, Latina wives appear to pull no punches when their man screws up. And often that is literal with the men sporting bruises to prove it. Either way, the man is in no way lacking for information about how the wife views the relationship and where he stands. But, he REEEEEEEAAAALLLY has to screw up enormously for her to leave.
On the other hand, typically a man with an Anglo wife will be swimming along quite happily in his marriage, spending lots of quality time with his wife and family, doting on her, making plans, only one day to have her say, "I want a divorce because seven years ago you made a comment/did something which I just can't get over." Of course, she will never have said anything prior to that, and the content of the offense will be something like a dirty pot left in the sink once.
So, based upon my observations, I have the following recommendations:
1) It doesn't matter how good of a husband you are or what you do. You have zero control over your Anglo wife leaving you. Don't harbor any expectations otherwise.
2) Just as men once dumped their wives for younger secretaries, etc., now women will dump their doting husband for a richer or better-looking man. Be very careful about marrying a woman much more attractive than you -- she may simply view you as the best guy "right now" until that war hero or wealthy businessman sweeps her off her feet.
3) Anglo women are much better at concealing their plans and putting up a false front. When she serves the papers, understand that this is the culmination of a multi-year plan. Don't waste your time asking her to go to counseling. Lawyer up ASAP and get ready for war; I guarantee she already has.
4) Understand that "asserting your authority" or "putting your foot down" about things like saving for the kids' college, or retirement, or giving to charity, rather than buying the big house or luxury car, probably will come back to bite you when some other guy with a big house and fancy car comes along. You have no authority except that which cir stances allow you.
5) All the talk about "being in this together" and commitment to the relationship, or being one person, etc., is every bit the song and dance it would be for the man who is manipulating his wife while dallying around outside. If you have su ions, they are probably correct.
6) Trust should be given verrrrryyyyy reluctantly to an Anglo woman. The Anglo woman who wants to get married real fast because she just can't bear to be without you is at least as likely to be putting on the long con as she is just an impulsive "romantic." And if you're a second husband and you fall for that, you're just stupid, quite frankly.
7) And to you men who still buy in to the Christianity nonsense, if you think you're somehow exempt because your sweet little wife can't stop talking about all the wonderful things Jesus is doing in her life, and half the Bible is splattered all over the walls of your living room, and you let her drag you along to the last 24 marriage conferences at your megachurch, you're going to be in for a big surprise when she decides that God's plan for her life involves a much higher standard of living than what you are providing, and that God's plan for your life apparently involves your not seeing your kids very much.
Or, do the smart thing, and decide that while alabaster skin, blue eyes, and blond hair may be nice to look at, bronze is likelier to last. Marry Latina.
