Hi from Just Answer. I'm PDtax, and will assist.
Since you were married more than 10 years, you will be eligible for a spousal benefit. And, it will not affect his benefit.
If you are divorced, but your marriage lasted 10 years or longer, you can receive benefits on your ex-spouse's record (even if he or she has remarried) if:
The benefit you are entitled to receive based on your own work is less than the benefit you would receive based on your ex-spouse's work.
The issue in your case is he is not entitled to claim benefits yet. He has to be at least 62 before you can claim a divorce benefit.

Thanks for asking at Just Answer. Positive feedback is appreciated. I'm PDtax.
