3. Accept that there is only so much you can control, and in reality that is just yourself.
4. Keep to the facts (as mentioned in the article)
5. Don't go out of your way to avoid them. Unless you want them to put you in positions where that is impossible more often, this is a big one.
6. They aren't just out to hurt you. Find ways to make it so you both get what you want. IE: If you feel you're being controlled a bit, let it happen but be mindful and set yourself limits.
