Male midlife crisis plus Russian female adventuress...never a good combination.
A family member lost her (middle aged) husband to a Russian girl they had brought over and hosted as an exchange student. Of course, as soon as she got the green card, she dumped him, and he also found out that she had been sleeping with her (much younger than he) Russian college student boyfriend virtually all the time they had been together.
Such is life.
Just like Mark Sanford found out his Argentinian “Soulmate” didn’t feel the same way about him.
