My crush has a crush on me!

I‘ve been told by various friends and classmates that a friend of mine who I developed a crush on since years also has a crush on me. Sounds great when you first hear it, but it is a bit more complicated and I feel very very anxious just be simply thinking about it. This girl is one of my classmates and by far the most popular girl in my whole school, she‘s pretty, smart, charismatic, confident about her self and just wayyy beyond my league. She is just perfect in any single was. Me on the other side wouldn’t consider myself popular or highly attractive. To be honest I am pretty a pretty basic person. If you walk into any other school you will probably find at least 70 people who are just like me, simply a side-character and by far nobody who gains lot of popularity and attention by other people. I also have very low self-esteem and was never in a relationship in my life. So basically we have complete opposite peoples. I thought about making a move but I am just too scared. Since i know her she had multiple relationships with other guys. They were all super attractive and when I mean attractive I mean abercrombie model attractive. They all drove the nicest cars, took her out to fancy restaurants, bought her designer clothes and even took her out on vacations. I’m even too broke to afford these things for my own. That‘s really intimidating to me, especially when you are competing against these guys. But She and I come along very good. We often sit next to eachother in class and even hang around after school. I would be the happiest man in the world if I were in a relationship with her, but I’m afraid I can‘t give her the perfect boyfriend she deserves. It almost feels like i‘m doing something illegal wanting this relationship and I personally feel very bad about it for some reason. What do you guys think about it , I could really need some advice!
