Curious: how do you deal with unresponsive investors?

Have others experienced investors going completely silent mid-conversation? I’m referring to situations where initial interest seems strong calls, follow-ups, even some diligence and then suddenly… no response at all. I fully understand that priorities shift and deals fall through, but the lack of closure can be a bit disorienting on the searcher side. Even a quick “no” would go a long way. Curious if this is a common experience in the community, and how you typically handle it. Appreciate any perspectives.
