What do you think about ghosting

I matched with this woman on Hinge, everything seemed great. Then as soon as we took it off the app her responses became slow and dull. We had one date. And then she started taking longer and longer to reply (days) we did talk on the phone since the date one week later but she's generally not giving out the same energy as when we started out. After leaving me on read for a whole day she replied to me this morning. I don't feel like taking things further anymore and just want to ghost her now.

I also deleted Hinge because I'm kinda sick of dating apps. Everyone is so fickle and ready to ghost and move on pretty easily (ironic, because that's what I'm about to do too). Idk if she thinks I unmatched her because I deleted my account but oh well.
