Ex-spousal Social Security Benefits

I have been divorced for 12 years and a friend told me that I should try to draw on my ex-husband's Social Security. I am on a fixed income and in a serious financial hardship and a few extra dollars would be a huge help. I called the SSA's "800" number and spoke to "Cindy". She took all my information; SS No.s mine and my ex's, etc. She put me on hold to get an answer. When she got back to me she told me that, yes, I would be entitled. Since I didn't have a marriage license from the state, she suggested that I order one from Vital Statistics in NJ which I did for a price of $60. I do have a marriage certificate from the church, but she wasn't sure if that would work. She then set up an appointment at the SSA office near me to complete the application. I went yesterday and met with "Jennifer" and after going over all the information, I was told that I was NOT eligible. I didn't understand the calculations, but it something to do with comparing SS benefits at age 66. I have been receiving benefits since I was 62. What a blow!! I can't believe one person can say one thing and another another person something else. I was extremely happy when I heard I was eligible, then I wasn't. I just sat down and cried. Now I'm out $60 for my marriage license which I probably won't need and back to square one finding ways to be financially secure.

I need advice.

Thanks,
