Besides any moral issue you might have, if you do cast a love spell and he does return.. theres a good chance that he will subconciously feel something is wrong. He could become argumentative, or simply feel like the relationship is "tying him down", or worse he could become obsessive and jealous.
To me, I would think that the probable concequences of forcing him back like that would harm the parts of the relationship you really seem to want most.
When I saw this, the main question I asked myself was:- 'Why is this in Covens?'' Nevertheless, Love spells, as Flagg said, can backfire terribly. They are a form of black magick and karma can come back to get you.
So be careful when you are doing a love spell. Also, if they are under a spell, is that really loving? Wouldnt you rather they just love you without being under a spell?
If you love someone, set them free. If it was meant to be, they'll come back.
Doing a love spell on a specific person is against the rule of three and think about it if the role was reversed would you want him to do that to you? Maybe try to take some time to get over not being with him. Then you can do a love spell to bring another person into your life just don't cast it on a specific person.
Love is not true unless you let the one you love do what feel will make happiest and if they truly love you with all their heart they'll find you are and embrace you in their arms and never let go. love is after all one of purest forms of power
