You may have a hard time getting along. Even though your lover likes to think things through carefully and logically, you don't want to follow their lead; you're used to acting and reacting, which may actually intimidate or at least annoy your partner. Things start out okay, but then all of a sudden you find yourselves in an argument, and often over the silliest subjects.
If you try to trace what happened, you find that some minor irritation occurred somewhere along the line, but instead of just glossing over it and moving on, you picked it up and ran with it, turning it into something much bigger than it ever needed to be. Misperceptions and projections run rampant between you; you see the other as being untruthful when really you aren't being completely aboveboard yourself, or you think that your partner is constantly spoiling for a fight when really you're the one that starts most of them. Even the more even-tempered of the two of you get into this kind of behavior; you just draw it out of each other, as if you can't stop from saying nasty, unnecessary things. Over time, you start to feel less like lovers and more like enemies, unless you can somehow figure out a way to nip this problem in the bud before it really gets going. Behavioral patterns are hard to break, and that's just what this will become if you let it.
