When you want it to be over and they don't

What happens when you've had enough of the bad behavior and want the other person to leave you alone? In a family situation, that might be easier to do since you may not live together. In a romantic relationship however, that can be a bit harder. What if the other person doesn't want to go? What do you do then? It's time to get clear on what you want so that you convey the right message that cannot be misinterpreted.
