Texted the guy by mistake!!!!! What can I do?

I just screwed up royally! Was texting my sister about this guy I went out on a date with Saturday night and sent it to the guy I went out with by mistake! He sent it to me and said, "I don't think this was meant for me." So embarrassed! What can I do? Background: I was telling my sister about... Show More

Update - I came clean! Told him he's right - the text was meant for my sister...that I was telling her what a great time I had, but that I have never visited a guy after just one date...I ended it with - I'm busted, but honest :)"

At least it is all 100% true. We'll see how it plays out, but I think honesty is the best policy. So embarrassing!
PS - I waited 30 minutes to respond and wanted to wait for answers on here, but I felt like the longer I waited to respond, the worse it looked!
