If you want her to like you than try being yourself and be kind, if that doesn't work than it wasn't ment to be. Don't waste your time on people who wont accept you for you. Ask her on a date and tell her to just give you a chance.
Forcing someone to love you is aganst the wiccan Reed and isn't kind. Not only that but you will be using a lot of energy to keep the spell up and eventually it will wear you down. Now you can do a spell to bring love to you, as long as you don't focus on a person besides youself. And also a spell to make you more attractive to others. I used a general love spell on myself when I was depressed. I felt as if I was alone and I did a spell, imagining myself being surrounded by people that loved me. That might work for you.
