Guy was asking me out, then I told him my recent ex is someone he knows... then he stopped responding, why?

So this guy has been after me for the last year but I was seeing a different guy off and on who I was crazy for. They both went to school together and were friends 10 years ago and are friends on social media. But they aren’t actual friends now and don’t see eachother.
So, this last week me and my ex ended things because it got too complicated due to outside factors although there are still feelings between us.
Guy 2 asked me out that night, so I said sure and he was super interested texting me until I asked him if he knew my ex (since I saw they were friends on social media) and he told me just what I wrote above. But he asked if we were cool and I said no, we broke up and it really hurt so I wanted to know if they were friends before we go out.
The whole night passed and he stopped responding. The next night I asked him when he wanted to go out, and he never responded back. It’s been 2 days since then and nothing.
Do you think he reached out to my ex? Would guys do that? Or did he just lose interest because of what I asked him?
