What's up guys?

So I am going to go over my last close. Every 'next step' became harder for me, not sure why.

I met the girl where she works. Always maintained eye contact, flirted, smiled etc. I got strong IOIs and kept up the dance with no problem. This was over the course of a week or so. So one day, while waiting, she stands at the counter and just stares at me and smiles. Obviously an invitation, as if the other subtleties weren't enough before.

So on this day I get her number. I asked her, and she complied enthusiastically. So now I have the number, and a date set up. Every time I go in, I get more and more nervous.

We went on first date, I was fine on the date. Date felt natural, we both had a good time. But I couldn't keep my frame when visiting her at work. I know she liked seeing me in there, because she always made sure to help me, smile at me, laugh when I spoke etc.

So I stop going in because I don't want to fuck it up before another date. Began to overthink every text etc.

So basically the initial dance was easy, got more nervous after getting the number, and even more nervous after a good first date. Ultimately the nervousness / shyness killed the "relationship" (don't know what else to call it, I don't mean relationship as in LTR or anything). She eventually ended up ghosting.

Shouldn't I feel more confident / comfortable after getting the number, and after a good first date? Anyone else experience this? And, is there any good way to remember to keep the good vibes going as things develop?

Thanks all.
