I'm trapped in a loveless mariage, with a narcissistic pervert and there is no escape in a short term horizon.

Moreover, I'm trapped in a country I deeply hate 

Divorce is off the table, I moved to her country because of blind love, here fathers aren't even considered more than trash and prenup where we married (in my country) isn't recognized. It means if she asks for a divorce she will get the kids, so my kids won't even talk my language as I'm the only one teaching them, she will take the house I paid for (if the negotiations stale for more than two years the mom gets it), half of my company, even if I'm only a freelancer.

What are my options? Divorce? Nope. Kill myself? Maybe when the kids will be adult. In the meantime? Suffering, day after day.
