When do you know something is worth giving a shot?

There’s this girl that I like and it’s weird from the moment I saw her I thought just this girls isn’t like any other girl ever. Then I started talking to her and it’s so weird she isn’t the traditional girl I know most guys would not improve of the content she makes and what she does. Yet she is one of the most beautiful open minded, caring, patient, understanding thoughtful woman I’ve ever met. But at the same time she doesn’t do all the typical things I expect girl to do when she likes a guy. We don’t live near each other so it’s hard see actions behind the intentions. But she shows it in other ways that alway surprise me I think that’s the biggest thing every time I expect her to do something that would show oh yeah this girl definitely doesn’t like me and is playing me. She does the opposite, for example I can be very clingy when I like a girl and a lot of cases to an unhealthy extent most girls when this happens just ignore me or block me or don’t wanna talk to me anymore. I think things were especially bad with her I did myself realize id taken things to far and apologized and told her the truth about what I’d done. And I was fully ready to lose her and have her no longer wanna talk to me. But all she did was tell me what the issue was and ask for a bit of space some breathing room. I’ve never had a girl do that or even when we were talking on the regular she could tell when I was holding back feelings that I didn't want to tell her. It still shocks me to this day that she could tell and wanted to talk about it with me and had asked on more than one occasion. The girls I know don’t do that in fact I’d say they more often then not just use it against you later. She so different that it’s almost hard for my mind to understand cause it’s not what I’m used to.
