21. Be Upfront About What You're Looking For
When people are younger, all these assumptions of settling down usually throw a wrench into the relationship, where talking about the future seemed like a taboo. More mature relationships act differently, where people are more relaxed and upfront about what they want. If you don't want this to lead to marriage, say it off the bat. If you're looking for your next big love, explain you're only interested in something serious. Don't leave any question marks floating around.
