My crush

So today I went to the park and I saw a really cute guy and then I realized that I had a serious crush on him but I was so shy to talk to him but then when I finally decided that I'll get his number so we can talk and everything, I went up to him and said "hi" with a HUGE blush on my face I was turning to red! He wanted me to sit and when I said okay my mom called me and was looking for me because it was too late and we had to leave the park for dinner, so I just got up and went to my mom! and the sad thing is we didn't even exchange numbers or anything and I literally can't get him out of my mind right now! What do I do??! :( I rally really wanna see him again
