Tell him you love him. Never knowing how he feels hurts almost as much as seeing him with someone else.

 Don't make a decision based on what he wants, the emotional pain is going to out weigh the physical pain ten fold.

 Don't try to grow up so fast. It'll happen in due time.

 Thank you for not marrying the guy I met when I was 17. At that age you don't know what you want.

 We were so thin and beautiful at 17. Break up with that guy you just met and live out your youth (trust me that 3-year relationship is not worth it!). You meet an amazing person later.

 There are many who didn't pay attention to their lessons and they're looking back and realizing they're idiots. Thank you Ms. Schuster.

 Yes, being "tough" and keeping everyone out will keep you from having your heartbroken, but you'll never truly be satisfied.

 Your relationship with the asshole your dating? It only gets worse. Dump him. Believe me, you CAN and WILL do better :)
