Are there veterans benefits available for senior veterans?

My husband is a Army Veteran and I am not eligible for any benefits because I am not a Veteran. We live in Texas.

If you are married to the veteran when he passes, you can collect spousal pay. It comes out of the Veterans check each month. But if you can prove that his death was war related, you can put in a claim. For example, exposure to Agent Orange, If the Veteran had been in Vietnam, and had prostate cancer, or Parkinson's disease. If you win your claim, you will receive his military check. When this happens, you qualify for a lot of the benefits as if you are the Veteran. You qualify for housing loans, If you are disabled, and need assistance in everyday living, you can put in a claim for Examination for Housebound Status or Permanent need for Regular Aid. One more thing, they will have to back pay you starting the month after his death.
