Search Results: guys waiting to call

So it is a long text today but you can answer in general.
For the record I am thinking that this might be the reason I am still single only brave girls approach me the others would give me a sign and then back off.
Here is the story, can you judge?
So, more than a year ago in KSA, at a hiking trip we were out as a big group plenty of new people I didn't know but I knew many (the orgrinzer and I had 8 friends of mine), I had to ride with other people as we had to go off road and there wasn't enough room with my friends, so we are in this car a guy and his father and one of my gym buddies, the guy doesn't know off road so I was guiding him through from the back seat as we had about 30km of off road suddenly as we too a stop to gather around a girl jump in the car and sits in the middle, first we introduce, I tell her that I would have to sit in the middle as I guide the guy cuz I don't want to bother you and keep leaning to the middle, she said it was okay, so as I amazed the passengers of how well I am good at knowing the off roads tips, we got to know each other well, and the girl kept close to me throughout the day, we hangout we did a hike and we got back, as they were Doing barbecue she was hungry but we had to wait till its done, and I was like "come with me" and I just stood there and asked for food and she was like "what !" everyone is waiting for food and you just go and ask and eat (as being the right hand of the organizer I had the right lol) we had a bit of argument about feminism and how the middle eastern men are and I was overwhelming her and won that lol, so at that day I preformed a couple songs on my guitar, and that was it.
The girl was all over me and she even took my number, but guess what.. She didn't call.
Is it that I was oveehmiling or inmidating?
by the way everyone was like okay man you got a girl lol
Sorry for the long text

So I've liked this girl at my job who is also my supervisor. Since I've been there I've tried complimenting her every now and then and asking how she's doing etc. But she never showed the same amount of interest as me and I felt like I wasn't making any progress so I kinda fell back and stopped making as much of an effort. Last week she called me during our break (she pretty much only texts me and even then it's only ever work related). But I was going through a low point in my depression so I talked myself out of answering the phone thinking that if it was important she would text me or call again. That entire week after not picking up her call I felt weird energy between us, she would walk right past me not saying a word or even looking at me but then smile and laugh with some other guy who just started there... Ever since then I can't stop thinking that I fucked up because I was too busy being petty trying to make her think I wasn't interested as some sort of revenge. And then just yesterday during our break I'm sitting in my car waiting to go back into work and I see her getting out of some other guys car smiling hard as fuck. I know I shouldn't be obsessing over her this hard but I can't help it, she's all I think about and it hurts me that I don't know how to just tell her how I feel without making it weird or awkward.
