Leah has Been Ghosted By Alex. She's Been Waiting For His Response.

Leah is trying to figure out why she’s being ghosted by Alex, a guy she met on Bumble. She really liked Alex and has been waiting for him to reach out but he still hasn’t. She says she texted him to thank him for the date, but his reply was really short and when she texted him again, he didn’t answer. What happened?
