How Do I Take The First Step ?!

Hello. I am a second year student in one of the largest cities in Bulgaria. Now the second semester in our specialty moved a girl with whom we immediately liked. Our specialty is still small (25) people and we communicate often since he came to us. I like her and I think she and my intuition almost never lied to me about these things. The problem, as the title implies, is that I don't know how to take the first step, and that bothers me a lot. I've only had one relationship so far in 2 and a half years, but then the girl took the first step and I generally got crazy and unrealistic luck, which will hardly ever happen again. We had met at a party and accordingly I was quite relaxed then she wrote to me and so on. We broke up because he went to study abroad after graduation and now we are just friends. You remember, that if she hadn't taken the first step, I wouldn't know what a girl is now, I'm just damn shy and I'm always afraid of confusing something and exposing myself. I have told girl friends about the gestures and hints of the girl from the course and everyone tells me that it is more than clear that I like her, I just do not know what to do and I get numb. There were times when we were alone with her somewhere, but we mostly talk about the university. It's as if sometimes he looks me in the eye and reads "go to hell do something", but I can't and I just can't. I'm not someone with a clumsy character, nor boring, everyone tells me I'm funny, just always behaving a little weird until I meet the person against me. I'm just shy and I always ask myself before I do something what will happen now when I say that, don't think of me as a fool, etc. It is very clear to me that if I delay a little longer, he will just give up on me, so I am writing here for advice. Thanks to everyone who read my story and I ask the moderators to publish it :)
