My best advice to you is DO NOT do anything that will impose on anyone's free will.
Both of my sisters did a binding spell on two guys. One was an ex-boyfriend and she just couldn't let go of, and now she's married to someone else and can't stop thinking about him. And my other sister bound her now boyfriend because she didn't want to be alone. And he wanted to leave her. (She was, before him, in a very bad relationship and she didn't want to be alone, so she felt this guy was her happily ever after. Well binding someones free will hasn't gone to good for either of them.
They both need/needed to do an unbinding spell to let them go. It's for the best.
This is just my advice.
If you really like this guy, go the old fashion way and talk to him and get to know him. Maybe something might happen. You never know, leave it in Fate's hands.
