How do I cast a spell and to make him go away?

So this guy keep making my life miserable, he makes me uncomfortable, gives me the creeps and just overall makes me feel sick when I’m around him. I’ve tried talking to him and getting away from him but nothing worked and now I am desperate so I want to cast a spell to get him away from me for good.<br><br>I’ve never cast a spell before, I have absolutely zero experience in this and I have only done some research where I heard that the red candle, black candle and some other stuff can bring this change.<br><br>Any help with this matter will be greatly appreciated.<br><br>TIA<br><br>Edit: I am not trying to harm him or anyone else to be honest, I have zero energy for that and I want him to go away so I could have peace and freedom to live my life to the fullest and to enjoy it without him ruining it.<br><br>And I want to thank each and every one of you for the advices and the help, thank you so so so much!
