Input: Consider Input: The difference is the level of commitment. "Dating" connotes a casual thing, not necessarily exclusive. When a person says "I'm dating Bill" instead of "Bill is my boyfriend", you can probably guess the relationship is relatively new and no commitment has been made.
When you've decided you're in a relationship, you'll probably start referring to one another as boyfriend/girlfriend. You'll introduce each other to your close friends and family. You'll likely spend a LOT of time together, and may take it for granted that you'll see each other certain nights and weekends. Depending on your lifestyle, you may agree to make your relationship exclusive and stop seeing other people.
If you're uncomfortable discussing taking things to "the next level" you're probably just dating, and not quite ready for a relationship.
Output: What is the difference between dating and in a relationship?
