I had a great first date with this guy but he told me he wouldn't go out with me again because he can't see us being "serious" together.

He is the second guy I actually liked. He was so cute and sweet. But then when I asked him if we would ever see each other again, he said that. Also he said that he wasn't vibing with me that much. I feel like I lost him because god damn he was hot as hell. 😂 I deleted him off my snapchat and deleted his number as well because I am so thankful I caught it so early (I "dated" a guy previously that rejected me when I asked him out.. I waited for him to ask me out for 6 months). What do you guys do when you feel like you lost someone (who was cute as hell too😂)?
