Let's say you're in a new relationship, and you're beginning to develop some pretty strong feelings (perhaps unexpectedly, too). Now, it's a good idea to see where your partner is. If there are signs you're thought of as a fling and not serious-commitment potential, it should be addressed early on before either person gets hurt. Of course, there's nothing wrong with having a fling, if both people are on board, but one-sided feelings are never a good thing, moving forward.
