As a single guy who went through a similar thing I can guess which town it was. Let’s just say that it’s a place where everyone is expected to be a certain type and older single or divorced guy just isn’t the norm.
I hope 100 is an exaggeration. I did find a few options there, none which I liked. And I didn’t call 100 people.
In retrospect I’m happy that I couldn’t find something there as I soon after relocated to a different city where I had no trouble renting as a single and was more matzliach in many ways.
Maybe consider a different place. Why live somewhere you aren’t wanted or respected?
