The third element I want to talk about is exchange—this is when two people give to and ___________ from each other. For example, they can help each other, ___________ things, and give love. The important point here is that people have to feel good about exchange in a relationship. Have you ever been in a relationship where one person gave more than the other? Was the relationship happy? Probably not. If two people feel good about their exchanges, they will continue in the relationship. And if not, the relationship can grow weak.
