This aspect is a difficult one to handle, as it brings up a lot of anger, resistance, rebellion and aggression between you. Even if your partner is usually very even-tempered, they can expect to be provoked constantly by you. They just aren't able to stay calm around you, and at times they get the feeling that you're actually provoking them on purpose -- which could be correct.
The ways that they express their anger at you tends to be overly extreme, because you really push their buttons and bring up deep feelings of anger and resentment. There is a feeling that you're trying to challenge them -- and even when that's not happening, they respond as if it is, and that starts the train rolling. Basically, with this aspect influencing your relationship, power struggles are almost impossible to avoid. So how do you deal with it? The best way to do so is to stop struggling -- to realize that you have no power over each other, not really, nor should you. Of course, that would try the patience of a saint! There are lessons to be learned here -- about not allowing your buttons to be pushed; about finding out where all that deep-rooted anger is really coming from -- but they're difficult lessons, and any positive effects are hard-won.
