Think logically. If you text someone with some urgent information that concerns them, they’ll get right back to you unless something prevents them.
The friend that never responded to the question about your qualities is strange. There must be some reason for the ghosting. I’d need more information to fully understand.
Either the love interest is into you or isn’t. Their ghosting says they aren’t. Take it at face value and move on.
In general, texts and email should be answered in a day or maybe a week. Heck, I had one answered months later. It’s like returning a telephone message. Nobody owes you an immediate response.
