My ex husband is angry I divorced him before he could divorce him? Help

So my ex husband disappeared completely vanished when I asked for divorce. Changed addresses phone number and so on. So years went by and I filed for divorce under abandonment and went through the proper channels to have a divorce by default when he failed to appear or respond. The divorce was granted years ago by a judge and the case was closed and sealed.

Years later my psycho of an ex went to court, started the same exact divorce case against me, in another state playing victim.

The courthouse was notified that we’ve actually been divorced for YEARS

And he’s looking for every which way to come after me for anything he can and press charges.

He’s basically angry I divorced him years ago and that he’s made himself look stupid and wasted money getting a divorce lawyer when he’s already divorced.

Can anything actually happen to me??? Can he do anything other than harass me? I moved on years ago and just want my peace could really use some comfort or advice please let me know if anything has happened to you like this
