While I think that Sabine, being wholly evil, looks at love as possession, I appreciate that there are other ways to see her "on camera" actions. (See about about minute 2:00 on the music video). I see Sabine taking a very proprietary interest in Nale, even though she points out to him that she has intimate relations with great frequency when they are not together. (Which is semi understandable, with her being a succubus ...)
So I've Learned That Love's Not Possession
And I've Learned That Love Won't Wait
Now I've Learned That Love Needs Expression
But I Learned Too Late
