Why do some guys stand girls up?

i was supposed to go on a date today with a guy i met on a dating app. he cancelled his other plans so he could meet with me which i thought was sweet. i was really nervous because i have only done online dating one time before. with the previous guy, i was also really nervous, but the dates were great, he told me on the first date i‘m very pretty and we ended up dating for some time before we broke up because he moved very far away. so i thought this time it could be fun as well. it gave me some confidence. however, i was waiting there for 20 minutes until he texted me that he was there. we didn‘t find each other right away and then i sent him my location. he then just said he‘s sorry but he has to go. i feel so insecure and he probably did it because he thought i was not pretty in person, right? i feel so awful about myself. why would a guy do this? has this happened to one of you as well? thank you for your replies, i would really appreciate it because i feel so sad🤍
