That is so cute! It's okay, it happens honestly. You never know with stuff like that but I know you'll be fine and okay, don't worry
I remember this one guy i met through one of my older friends at the time. His name was Jedi and honestly, he was cute. He was 31 (or 34, i forgot lol) and i barely turned 18. He was tall, pretty skinny, but god damn it I thought he was handsome as hell. So we were texting for a bit and then he asked if I wanted to hang out for a bit. So he picked me up on Friday night and we went over to his house for a bit and oh my god, the connection was crazy.
We could talk about EVERYTHING. He even made 21 questions fun and sexy. Then i spent the night (well, the whole weekend) and it was crazy good. Like, tbh idk if it was our connection, if he was older and settled, or what but i felt myself falling for him over the span of a weekend (

). He was, truly perfect for me honestly. Then when he was taking me home, his car broke down and he had his friend toke me home (his friend was creepy as hell and gave me weirdo vibes).
Then after that, we texted on/off but we didn't hang out cause his car wasn't fixed. then i deleted his number on accident. then around later that year he texted me and we made plans but then he never got back to me. EVen though it's kinda not like your situation, i still know the feeling of a missed opportunity and it sucks. Yeah i think about it every once in a while but it's life. we deal with mess, get stronger, and keep it going. You'll be alright, i guarantee it.
