Why would a guy left me on read after 1st date but not unmatch me?

Had a great 1st date with a man. We had wine, conversation and chemistry. The next night he texted me asking g how my day was, I responded and asked him a question, he read my text... it's been over 24 hrs no response, okay he's just not that interested, but why keep matched on the dating app?
