Alex. If you want to get with this girl I want you to do two things:
1.) Ask yourself, "How does her friendship benefit me more than her being my girl friend?" Meaning, what does she provide and bring to the table in your platonic relationship? Also I hate to say this because I come off as an asshole, but what about her social value? Is she well connected? Can you network through her?
2.) Ask yourself, "What to find attractive about this girl?" Really meditate on the idea and why you want to escalate your relationship with her to that of mates. Then do the complete opposite! Find all her flaws and what you don't like about her. A good example of this: (A girl I once knew, my friend, had me all into her one day and then I started to fall for her. Anyhow I asked myself why am I so into her? The other guy in me was, "she's socially awkward, and she doesn't give OR receive oral sex...etc..."
Find her flaws and ask yourself can you live with those flaws? Find and meet or know already girls that don't have these flaws that are the same caliber on sexual attraction as this girl and tell me what you think.
I can not tell how to get with her or sleep with her. All I can tell you is how to go about thinking about it and weighing your options. I just got into the game like 4 months ago and before then I would get friend zoned fucking hard by a lot of girls.
Honestly a lot of men say that once you are in that zone, it's impossible to get out. You can date her, but you will just end up breaking up. To have casual sex as friends I would just tell her you are attracted to her and kino her some.
Hope this wall of text helps you.
