In that case.... Maybe an allowance on a certain strength of the spell, so that as long as the person has the will to fight against it, it doesn't work. Or the spell could only enhance the feelings that the person has for another, so it's not taking away the freedom to choose, but just making one seem more appealing to another. On the flip side to that, if the person has no interest in the one using the charm spell, then the spell is rendered useless.
