Hello, I'm new here and just looking for help.

So, I'm 21 years old and during my entire life I never liked any girls. Sure, I was sexually attracted to them but I never had romantic feelings towards any girl. I didn't really care about it.
Well this new girl came to the college I currently go to and she's in my class. For the first time EVER I felt interested in a girl this way.
I've known her for about 3 months.
I'm pretty sure she likes me too. But I don't wanna assume anything. I'm very confident in myself and consider myself an attractive person.
I wear my earphones everywhere I go, always. She started doing it as well a few weeks after she met me.
I eat an apple every day on my way to college since I don't have time for breakfast at home. She sees me on the way and guess what? She started eating apples in front of me. She started to even imitate some of my body language. I really don't wanna assume anything but I really do think she likes me. We also have VERY STRONG eye contact. Every time our glances meet it feels like an eternity. She's very shy around me and gets to the point where her legs shake. I'm very interested in her, and for the first time, it's not about the body. She doesn't have big tits, doesn't have a big ass, just has a great personality and is nice with everyone.
The thing is, I'm scared.
Why am I scared? Well, I'm pretty young and never had anyone as my partner. I have absolutely no idea how to have a relationship.
I also don't have a job since I'm in college and I don't have money of my own yet. I feel like if I were to have a partner I would like to treat her properly, taking her to dinner, to the cinema, etc. But I really can't do that. We're both from different cities studying in the same city which also kind of complicates things. I've been meaning to talk to her for a long time but I'm scared of wichever the answer is.
If she does say yes, (interested in me) I will have no idea what to do. What's the next step? Do we just walk around with the "couple" lable?
If she says no, well then I'm just gonna be sad because for the first time ever in my life I like a girl, and I'm not corresponded.
I've had several girls say they like me but I rejected all of them for the simple fact I did not like them.
I'm also scared it's something like a crush. I overheard her talk to a friend and she said "She falls in love easily". Wich, with all respect, to me makes no sense. I'm very scared she just sees me as a crush because I have a pretty face. I don't want that. I wanted it to last. I really do think she's special.
I have no idea how to approach her and I'm scared of witchever scenario comes up.
I would like some help please.

Worst case scenario she says no. I think you should definitely ask her out sometime, because she is definetely showing some interest in you and I think you could get to know her and eventually date her.

Hello there my friend, I am you from the past 27 now, and looking at your post is like looking at the mirror, all I can say is you need to sit with yourself and figure out what you want to do, Im not going to lie to you relationships are a responsibility they require efforts and trust and sacrifices and im not really sure you want to do that (unless you do) Also no number of explanations will ever give you an idea unless you actually try yourself and see, I say date her, be a man approach her and ask her for coffee, talk about your headset music etc you have nothing to lose, best case scenario shes the one that might make you head over heels, or she will be a lesson you will learn from and to be honest we live in a life where guess what you learn from mistakes good and bad ones so I say man go for it you have nothing to lose and dont be scared, If i had a future me writing to me telling to suck it up and go maybe i wouldve used the opportunities that I got

goodluck mate ;

If you really like her, so go and get her,
Good luck for you .
