just tell her how you feel and ask her on a date. if you're so concerned you could make a honey jar, but no love spell will work if you're not able to be yourself and ask her out. i get it's scary to ask someone out but if you're friendship is walking the line of friend/dating, i'd take the plunge.
If you are already speaking with this individual, then take some initiative and make plans together, this way you will be spending time together and getting to understand if there is chemistry between you. It does not have to be a date, just plan events, concerts, movies and such, even with a group of people. If you have difficulty running into her then take some steps in making sure you are going to get the opportunity to spend time together.
A honey jar spell is a safe start to help encourage a likable disposition with her. You can also carry an avocado seed to promote beauty and attractiveness and attract individuals with pleasing dispositions.
You don't need to be an expert in love, or need to hire someone to cast a spell for you. Just try making some motivated efforts to getting to know her. If there is interest in return she will want to spend more time with you.
Listen, apparently I must have said something wrong. I have been talking to this girl nearly everyday. We have good conversations all the time. And by all the time, I mean the only time I see her. She is usually busy, and her friends are usually around. She has the type of friends that are defensive for her relationship. All I am asking is that I can get a spell cast for some good luck to where, let's say, a certain friend doesn't show up, and I have the girl all to myself to start a deeper conversation without any overprotective gal pals butting in. The friends and the time are the biggest problems, and I have no control over them. I wouldn't request this if I didn't have any problems I couldn't change myself.
Her overprotective friends, as you put it, shouldn't be allowed to get in your way. If you can't face them, and she won't stop them, that should be a red flag.
Regardless of how you feel towards her, if she's not returning the affection, no amount of ritual will change that.
As others have already pointed out, if you want a spell done you'll have to do it yourself.
If you're not up to creating a sweet jar, you can always set a lit pink candle by your open window. Or place one piece of green yarn, and one piece of pink yarn, under your pillow at night. This should allow your intent to stimulate your dreams and hopefully give the answers that you seek.
I would try to cast a spell yourself. Putting your own energy into a spell or any kind of working is always the best option. You don't need a lot to do spellwork, in fact you don't need any ingredients or tools for a spell. They're just their to help the caster focus their intention towards what they wish to achieve. I would look into spells to surround you with love attracting energies or even a spell to attract a closer friendship. Surrounding yourself with these energies may help bring people closer to you and may even help to bring her closer. You can try making a charm to keep on you even with just herbs you have in your kitchen or even writing down a symbol, a rune, or words on paper, folding it, and putting that intention into it. Runes that symbolize love or friendship, or common household herbs that help bring love and friendship to you, maybe even writing the intention down in colored ink with the right color to bring love and friendship to you. These are all just ideas that are cost friendly and effective. Do your research, and you will find something that works for you. And if a spell doesn't work the first time, try another method and switching things up. I hope this can inspire you to try c: If you ever need help feel free to ask!
