You two are in touch with some deep energies during this period, which you'll need; you're running into resistance from all sides now, and only real determination will carry you through. Teamwork makes things easier, of course; but your best course is to temper that combined determination with some social tact and grace. If you try to ram your way through walls -- bullying your bank into giving you a better APR on your credit card, for example, or yelling at the umpire on your intramural soccer team rather than being diplomatic about a bad call -- will only hurt you two in the end.
If you start to notice other people being overly aggressive with you when you're trying to get something that you want, take it as a sign that you're being overly aggressive yourselves, and back down a bit. You catch more flies with honey, as they say. But most of all, flexibility is key during the next few months. Even though you two are functioning as a real team now, that doesn't mean everyone else agrees with you. When you're working on a project or playing a game with other people, make sure that you stay open to their ideas and input.
