Separation From Current Relationship

I need help in deciding which candle to purchase. I was up in the air between Legba because I do want to build a stronger relationship with him for work I will need in the future. Here's my dilemma. I'm over my current relationship!! I've tried to break up with him, I've kicked him out, you name it. I cant get rid of this man and I'm genuinely over it. I dont want to get the police involved cause I'm sure he'll stalk me and it wont get better. I just want him to go away! in peace, live his life without me. Dont love me, think of me....just disappear without harm to us both. Will Separation work for that? Or Legba to remove obstacles? Please HELP! Looking to place the order asap!
