I've never felt this way before

So a guy messaged me on Grindr yesterday. I almost didn't respond since he didn't have a face pic, but I decided to entertain it. Right off the bat, he's clever and witty. I send him a quick voice message several messages in and tell him that I'll be responding this way for a bit because I decided to go on a drive and listen to some music. He responded immediately and said something like, "how about you just call me?" I've got a lot of social anxiety so this was a daunting request initially but I decided to say "fuck it, yeah let's do that."

We talked for 3 and a half hours until like 2:30a. We talked about family trauma and dynamics, we talked about my current kinda not ideal living situation, I told him about my overdose, my struggles with alcoholism. I love the way his brain works. He's curious, concerned, engaged, and extremely intelligent. He's willing to share his own experiences and traumas. I got off of that phone call feeling like something important just happened to me. Something big.

Today, we decided to grab dinner. He's handsome, like really handsome. He's polite and humble and self-aware. Dinner was amazing and then we went to my car to listen to some music together and make out. We held each other for a good long while and both agreed that this feels big and important. I could tell that we were both kinda holding back and trying not to say something too big so as to scare the other away, but I came away with the feeling that we are 100% on the exact same page.

Guys, what the fuck is happening right now?? I feel like I'm back in middle school with my first crush. I'm cooked y'all. Well done. I just had to share this experience somewhere. Any advice on not fucking it up?
