am i crazy??!???!!

So I met this guy back in January 2020 he was in my class in college and we had a group project together and i kinda flirted lowkey with him back then, but it didn’t seem like it was going anywhere, so i started talking to this new guy and he treated me okay until our school got shut down for covid, and after that he was awful to me. so i ended up breaking up with him in july after trying to end things and failing 3 times. anyway in that time the boy from class in january and i hadn’t talked but his dad sold my dad my new car and they talked about us going to the same small college and both being athletes and and whatnot...anyway flash forward a month and we were both on tinder (i know college cringe but whatever) and we matched so i invited him to hangout and i also found out he had been crushing on me since that day we met in January and had kinda checked up on my social media to see if i was still in a relationship before he saw me on tinder hahah and it’s been basically non stop since then, we never have a bad time together, he treats me like a QUEEN, and when i look at him i see forever, and i’ve dated other guys before but i have never dreamed of a more perfect guy for me. he told me about a week ago he loved me and while i thought he was crazy i said it back. i mean it is in normal standards. but i don’t know. i guess what i’m asking is am i crazy to think i might have found my person for life at literally 20 years old? but it all just kinda seems meant to be, like we grew up 20 minutes down the road from each other playing sports at the same complex for 5 year and just never hung out (except for working on a project) until after our dads met? idk any pieces of advice to keep this amazing man around in my life?
