Ex tried to exchange sexual fantasy for $ he owed me

My ex owed me $8000 for stuff he "promised" to pay me for plus 2 notarized statements of 2 things he purchased from me and never paid for. Anyhow, I am FINALLY down to the last $450 from 2016. It took a lot of struggling, but I did it!

The other day he wanted to exchange one of his sexual fantasies for the last $450.00. Wft?! Get the hell out. Watch him get extremely pissed. I have cropped out names and photos for privacy. This was a random conversation HE started out of nowhere. Hes gray I'm orange.
