Question about divorce & military buy back

Hello, I cannot seem to find this answer through my searches. I hope someone here could help. I needed up not doing the full 20 years of service meaning I did not get a military pension. I got divorced in 2018 after 10 years with the ex getting military pension pay in the divorce decree. My question is if I buy back my military time, 16 years, will I have to pay my ex?
