Yes, it can grow and come out any time. Sometimes all it needs is time and/or the right situation to come up that brings the two together in that way. I don't know if I would have the patience to give it a chance to grow if there wasn't some degree of spark or something special there.
Yes, i believe it can take time for the chemistry to happen between 2 people in a relationship It can be described in the terms of mutual feelings a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction... brain chemicals are definitely involved.
It can; however, I notice that a lot of women don't let that happen. If they don't feel a connection within the first 5 minutes of a date, there won't be a 2nd date.
I am not trying to be sexist, I am just looking at this from a male perspective since this has happened to me many times.
That is why I think people should go out on more than 1 date before making decisions.. Because in my opinion, the first date isn't always the best date... it can be, but a lot of the time the guy is too nervous or the girl is too nervous.
in time it can but not always
I'm not going to answer your question, rather I'm going to tackle what you've raised in your comments.
"He listens to my stories, but never shares an opinion. It's like he doesn't care to hear."
From what you say, he's really into you, and likely wants to communicate well with you. The issue may not be that he's 'not listening' but that you aren't getting what you want from the conversations.
I suspect what he's doing is actually learned (though maybe not).
Most guys, when a girl tells them stories, offer solutions to problems. This makes a lot of women mad, it makes them feel like he doesn't care to hear about her feelings and just wants to 'fix' her so he doesn't have to hear about it. (It's generally meant as the opposite - guys want to help fix because they care, and guys give advice to each other rather then simply doing things partly as a way of demonstrating confidence).
Anyway... he's not reacting the way you'd like, but he may not know what it is you'd like him to do. I can guess, but I might be wrong.
But I'd suggest directly telling him what you're looking for emotionally when you share stories with him. If he's as into you as he says, he will want to not just 'do what was asked', but will be happy to be able to emotionally support you once he knows how to do it!
You must have chemistry to have a fulfilled, successful relationship. It doesn't always happen on the first date, though. First dates can be awkward, both people putting their best foot forward and being a little tense. If by the second or third date you don't feel the "click," it probably isn't there. Chemistry is different than attraction. Attraction can grow over time. Chemistry is that click in your brain that says you will be a great match.
I went through this myself, I met this guy on tinder. We talked for awhile a d I thought he was sweet but when we met in person it just felt like 2 friends talking and I didn't have that romantic feeling that I thought I should, a few more dates and I just wasn't getting that spark I wanted and I hated it because I liked him a lot, I hadn't felt that way about anyone in awhile, so we date for a few months and then one day something happened, we were just sitting there watching tv, talking and lauging and I fell asleep in his arms the way that he made me feel so safe and wanted, I woke up to him kissing my forehead that seemed to reach my soul lol, sometimes it just takes a little time, timing is everything, if its going to happen, it will happen when its supposed to :) :) :)
