married filing seperately with 1095a

My set of circumstances is that my now ex would not file his self employment taxes. Finally got him to an accountant in 2015 to file 2013 to 2017. Again, did not file taxes and it is now 2025. I divorced in Feb 2024 due to this mess.  So I am retired as of Jan 2023 at 62. (I would not have retired had I known I would be getting a divorce. The divorce filing was to hopefully set a fire under him to get him to get his things in order. Fail.)  I get a 1095a for health insurance. In order to keep getting health insurance they want my 2022 and 2023 1095s filed. So I know I need to file Married filing seperately for those 2 years. Do I file my own medical, etc. And he files his self employment papers under his? I live in a state where Social Security is not taxed but I have 10 percent taken out to get health insurance. (You have to file taxes to receive.

Thank you for any ideas on this mess!!
