Can anyone relate?

I broke up with my ex two months ago after finding out he cheated on me for almost a year. He reached out to me today, explained he’s facing homelessness, and asked to sleep on the couch at my place until he finds a new job and gets back on his feet. I have absolutely no interest in dating him again, but l hate the thought of anyone being homeless. If anyone has helped an ex facing homelessness, hearing your experience would be greatly appreciated. And if you can’t relate personally, l would still appreciate hearing other people’s insight.
