This is a spell I've used a few times, it worked every time.
Get a rose, or any other flower if you can't find one.
Carve your name and the targets name onto the candle, then get 2 pieces of paper and put your name on one, targets name on the other.
Light the candle and say
"You and I we shall be one, by loves true power this spells begun, you'll give your love and I'll give mine too, by loves true power it cometh true, you'll give your love from thee to me, by loves true power SO MOTE IT BE. Let love and light within you shine, by loves true power you now are mine"
Say that 3 times, each time imaging the person running towards you, and on the end of the 3rd time imagine them hugging you and saying "I love you (your name) for always". Now let the candle burn out, doesn't matter if you can't but best to let it.
Go outside because you are going to bury something.
Take the paper with his name, crumple it up, wrap your paper around it and put it inside the flower, and close the petals.
Dig a little hole, put the flower into it and say
"As this flower withers, so do your defences against me, from this day forth we shall be together in deepest love"
Now cover with the soil.
I got this from a book years ago, and it works pretty quickly for me.
