When you get together this week, you'll both be running off at the mouth -- talking, arguing, monologuing... At the moment, neither of you has any sense of when enough is enough; you'll just keep on talking, or yelling, unless someone (such as your sweetie) stops you. And how will they stop you?
By saying something that upsets or offends you, probably because you've misheard them -- because who can listen carefully when they're talking as much and as fast as you will be? It's not just you, either; your sweetie is doing the same thing, and you both need to take a mutual chill pill. Try to listen instead of exaggerating. Another possibility now is that, instead of arguing, you'll be in agreement -- but neither of you has any real sense of reality or perspective at the moment. You could talk each other into a frenzy over something that's really a minor thing, or something that you've misinterpreted from the start. Try to keep in mind that if something seems too good to be true, it probably is; and if you're suddenly up in arms over something or someone, it has more to do with your current state of mind than with them, or with reality.
