This paper describes tests on CR2032 under "high current" conditions and shows that short 15 mA bursts are not that harmful. https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/104/7510.swra349-Coin-cells-and-peak-current-draw.pdf
The average current draw has a huge effect on battery capacity and lifetime, as documented here. https://www.dmcinfo.com/Portals/0/Blog%20Files/High%20pulse%20drain%20impact%20on%20CR2032%20coin%20cell%20battery%20capacity.pdf

I imagine that the OP's setup draws maybe 10 mA on average, so the lifetime estimate in the reply #3 above is not applicable.
