My ex F58 and I got divorced 15 years ago. As a male, I read the ex-wife is entitled to the husbands Social Security Benefits (50%). I am M61 and learned that as long as we were married 10 years or longer, I am eligible for half her benefits because, she forfeits my benefits because she got remarried last year. I never remarried.

For 20 years I had tremendous expenses for mortgage,Child support, family lawyers, divorce lawyers, two college tuitions and marital debt. My retirement is impacted drained 401k. Can I pursue her benefits?
