It could, but on the flip side, it may also be demonstrative of emotional catharsis, supreme emotional understanding and support.

@k1hodgman - supreme emotional understanding and support? even if its the square between the two people?

I have seen this dynamic play out like a cat playing with a ball of yarn..or better yet a mouse that it has in its clutches and toys with before it finalizes the kill. The thing is I absolutely don't understand this. It seems that, the Pluto person abuses, simply because they can and the moon person always seems to have their vulnerbilities exposed for the abuse.

If the Pluto partner were responsible with their power, made the effort, and were supremely self-aware then sure!

@ k1hodgman.. but wouldn't that represent the trine? I'm not trying to be difficult here, just really trying to get a full understanding.

It's no problem, your not being difficult at all.

Easy aspects (trines+sextiles), whether in an individual or between individuals, are harmonious, and come easily and naturally. That's great and all, but they don't push you to be more than you are.

Hard aspects (conjunctions, opposition+squares), cause friction, and practically force you to push yourself to resolve the conflict. Now this might result in the union between two people breaking, or it will push you and the other to be more than what you were, resulting in the relationship to be more intimate and powerful than what an 'average' relationship can provide.

It's a matter of taste really. Do you prefer your relationships to be harmonious and free-flowing? Or do you prefer them to be intense and emotionally charged, and for the other person to 'push' you?
