Be willing to explain yourselves carefully and compromise a lot, because you need both those elements in place in order for things to run smoothly between you. The ways that each of you naturally think and communicate are at odds with each other; mentally, you find you're as opposite as an introvert and an extrovert. You have a hard time understanding each other, even though you might try hard to figure out where the other is coming from.
Little misunderstandings lead to larger frustrations, and you just don't feel completely at ease around each other. You have a hard time making plans together and sticking to them, because something always gets lost in translation between you. Needless to say, this is difficult to deal with, but it's worth remembering that it isn't the explicit fault of either of you. Since your communication is hindered by some sort of obstacle that is hard to pinpoint, you have to remind yourselves repeatedly -- don't jump to conclusions. Don't assume you know what the other person means, and don't read between the lines. Instead, make the extra effort to tell each other exactly where you stand on an issue and why. If you want the relationship to last and to be satisfying for both of you, you have to learn to compromise, to talk out your problems and act more as a team than as two individuals with different aims.
