I just recently started preparing to cast my first spell that deals with some one else. I am a little confused, My boyfriend and I recently broke up. He immediately went back to his ex, problem is she uses drugs by needle and therefore when he is with her he started back using them by needle as well, It took so long to help him stop when I met him, Now I cant even see him to try and talk to him, I thought of using a banishing spell but I want to to stop him from having the urge to do this , I keep picturing him throwing all his needles away, But I cant figure out which would be the best spell, Can someone please point me in a direction to figure this out.. Thank you for your time
