TIFU by crying on a date

Good morning to everyone who didn't wake up crying their eyes out. So, buckle up cause this one is really weird. I (22m) went on a third date with a girl (24f) last night, and i did something that you usually do maybe after some time into an actual relationship and not after 3 dates.

So this girl, let's call her 'k', a really sweet woman, for me it is the first time dating someone that has past experiences in dating and in relation because the relationships i had been on were with girls who this was their first time. The first two dates with her were great! We had a lot in common, we chatted over the phone quite a lot after the dates and last night was the third. We decided to play snooker together and it was really fun for the two of us, but what we really wanted wad just to take each other's clothes off and make out. The vibe was just right. After the snooker we went and got ice cream, and after that, we wanted to find a quiet place just for the two of us. We didn't want to take things back straight to one of our places because we don't want to rush into sex. (Not saving ourselves untill marriage, just not hurrying). So we go to the beach, find a nice place and we start talking, making out, talking, making out, you know the drill. At some point i wanted just to talk with her, i really felt a connection with her and i felt like I needed to vent some of the things that have been keeping my peace. At some point, i was on the edge of crying and some part of my brain thought it will be okay to lay my head on her lap and just let some of it out. In my mind, I'm showing her how safe I feel with her and how open i am about things. Keep in mind folks, date 3. So after a little sob and her petting me a little, i get up, and the coin drops. I just cried on a girl's lap on our third date, this probably was wayyyy too soon to do. I look at her and she is just baffled. I started panicking. Hard. I really liked this girl (gave her a small blue french horn from HIMYM on the second date) and in my mind i just threw all of what we had built out the window. I start apologizing and suddenly i get real dizzy, i feel like I'm about to pass out. Then i did, for a few seconds. When I asked her if she is okay she didn't know what to say. All i wanted to hear from her at that point was: "yes, it was way too soon to do that, but it's okay, i still want to go out with you" , but all she said was that she needs time to think and that it was getting late. After resting a little more from passing out, we walked back to my car. We were holding hands on the way back (not for the first time) so that really helped calming my overthinking head. Driving back to her place i started yawning non stop so that was my body's way of saying, 'hey, get some sleep'. I drop her off at her place, she gives me a kiss on the cheek and asks me to let her know when I'm home. Before she leaves the car, i asked her just to text me tomorrow (today) because i am really worried i ruined what could have been a great relationship. She says okay and leaves.

At the time of writing this, it is the morning after and I'm basically waiting for her to wake up so we could talk. I just hope she will be able to see past that thing i did wayyyy too early on in a relationship and we will continue dating, but at the moment, i really don't know.

Okay, more background on things: Me and K met on an online dating app, first date was bowling , second date was a picnic on the beach and that was the third. She lives a little far from me but over the weekends when she stays at her parents house we are closer. We talked about the long distance thing and we think it will work.

Tl;DR: cried on my third date's lap, now overthinking if i ruined the beginning of the relationship.
