You remember she is a person and would want to give herself to you, rather than you 'getting' her. If the the attraction isn't mutual, drop it and move on.
Just talk, see if there is a spark or click between both of you, if there is, let it unfold naturally, if not, look elsewhere. Once the spark is found one can then think about magic, but it truly shouldn't be necessary so early on. Finding a person whom you can grow to love naturally without relying on magic is much more beneficial to you.
Talk to her, ask her out for a date. You know, regular things.
You cannot trick a person into loving you. A spell cannot create a spark that isn't there. You might be able to seduce them, but when, and I do mean when, they will wake up and see how manipulative and wrong it is. And they will leave.
I recommend just asking her out. Man up, do what men have done for all of history, and get some courage.
