The speaker is deeply in love, so much that they love their partner more than themselves. That love is painful, since it "tears me apart," yet it also holds the speaker together, linking heart, soul and mind. Their "inner demons," which seem to stand for self-doubt or inner darkness, vanish when the loved one is near and return as soon as that voice and touch are gone. The speaker depends on this person for relief, and that dependence is the poem's quiet tension.
The mood starts out warm and devoted, almost awestruck, as the speaker calls the love "magic." The last line shifts it. The speaker wonders whether the magic weakens the demons or simply affects the speaker more. That doubt leaves an uneasy note: the love may heal, or it may bind the speaker more tightly. The title, "My hate for our love," hints that the speaker feels both gratitude and resentment, and the poem never fully settles which wins out.
