@Your_Moms_Beautiful Now, I may be over a month late, but I got you covered. The same thing has happened to me. Are you two not speaking at all, or is it just that you aren't as close anymore? Depending on the answer, you could do one of two things:
1. You can try to become a bit closer, and rebuild the close friendship that you once had, eventually leading up to you asking her out, or just remaining close friends. OR. Try the alternative, and cut off all ties with her so that way you never have to speak to her again. Me personally, I think the first would have better outcomes.
OR
2. You distract yourself enough from your thoughts of her, and keep yourself busy. Potentially cut off all ties if you have to. Maybe try avoiding certain things that remind you of her. Don't go looking for another person to be in love with either, that will only give your hopes up and will leave you hopeless. Rather, let love opportunities come to you.
I do hope this helps, and I'm sending you my best wishes! <3
