Firstly, you have to think to yourself, how much do I understand about magick? and why do I need him back?
Sometimes people are not meant to be together, so forcing it may not be a good idea.
Magick in all forms requires some knowledge, we don't know how new or advanced you are.
I would say that instead of persuing a magickal answer, maybe try for a mundane one, talk to him, find out what he thinks about the chances of you two being friends and then maybe more.
Often forcing someone to be with you, if they don't want to, can do more harm than good in the longrun.
Best of luck.
