My heart is broken and I want to get back at him. I knew my boyfriend for years, he is a childhood friend, so I crush formed and I started to love him. Then I found out didn't want me as his girlfriend because he refused to see me and he didn't want labels. He used my affection towards him so he can have attention. I don't think he should get away with it because it was cruel. Because of him I had a panic attack because he made me feel worthless. My philosophy is if someone is going to jump flower to flower then they should be treated like a son of a bee. Is there a spell I can use to give him karma but won't backfire on me? Please and thank you.
