Get a white candle that will burn down in the amount of time you have to watch it burn down completely. You will have to inscribe it (see below), so it should be bigger than a birthday candle, and you will also have to watch it burn down to nothing, so it should not be a long burning or large candle. A plain white altar candle or, better yet, a white "bride and groom" figural candle, will be right.
Prepare an altar and decorate it with items that are precious to you and to the one you love. Using a rose thorn from a white rose bush, inscribe the words "All my love come to me" 3 times on the candle. Place the inscribed candle in the center of the altar and light it. For the entire time the candle burns, gaze upon it and visualize your love coming to you in nakedness and beauty. When the candle burns out, collect the wax puddle that remains, wrap it up with the mementoes from the altar and keep it in a safe place.
The result of this spell will not be "zombie" or "victim" thrall-love; but you will receive ALL the love that person has for you -- which may be less than, as much as, or more than the love you have for him. Accept the degree of love you receive with grace and tenderness.
If at some future time you no longer wish to receive that person's love, dispose of the ritual remains in a simple ceremonial way. Depending on your mood, the wax puddle can be burned on a fire, buried at a crossroads, thrown into running water, mailed to the person, ground to shavings and baked into a cake -- or whatever you feel is appropriate. But it is your responsibility to dispose of it if you no longer want to be loved in any degree by that person.
