I got Reality-Altering Powers. Which apparently technically means I'm also Omnipotent, but for these purposes, we'll ignore that for the moment, since the point of this isn't really to prove that two Overdeities can probably figure out a way around each other's defenses.
I have
Omnilock, so I step outside all realities, including the one you exist in, meaning I can't be directly observed or affected by you. You can surmise my existence from suffiecent evidence, if I slip up, but that's about it; as soon as you enter the non-space I'm in to try to get at me, it becomes a reality, and I vanish from it.
I then use
Nonexistence on any romantic love and/or attraction any significant other you might have feels for you, and on the concept that they might do so.
Then I use
Reality Warping to make it so that a thing can both exist and not exist at the same time outside of thought experiments, Nonexistence to erase the concept that it was ever not that way, and Creation to make an empath who is blissfully unaware that they contain such a substance (which, theoretically, you and your powers will also be unaware of, since it counts as not existing), and attracted to you, then place them where they'll be set up so that it should be reasonably easy for them to use their knowledge of your emotions to get into a relationship with you, and use Nonexistence on the concept of their not having existed prior to when I created them, as well as that of their not having been born normally and lived a reasonably normal life.
Should that work and you become reasonably intimate with them, some the non-but-also-not-non-existent substance should get into your body, where it bonds to you and becomes recognized as a part of yourself since even as it's doing that, it doesn't exist, and thus doesn't count as a change, at which time I use Reality Warping again, to remove the first substance from the empath I made, and replace it with another, which, when it combines with the first, is an incredibly lethal toxin, which, presumably, will be counted as part of your body's normal function, since the first half of the toxin is now being counted as part of you, and has as its purpose bonding with the second half.
