I'll try. I believe the critical question is "Is she also waiting for Mbo?" Or better yet, "Is she even aware that Mbo is waiting for her?" Before you take offense at this Mbo, I have to confess that I just found out that the man I was "waiting for" was keeping his options open. My option, as you gentlemen (and trust me this is not the first word that comes to mind to describe the opposite sex today) say in football, was dropped. You are too young to know that this is the ONE woman in the world for you. You are being unfair to yourself. And if that isn't enough to make you reconsider your options, you are being unfair to her.
I am not suggesting you run out and get laid or even date formally. I am suggesting that you allow yourself to meet other people. If SHE is in fact The One, I am happy for you. If you find yourself attracted to someone else, give it some thought.

Lecture over. You would be perfectly justified in telling me and the "cat's rear foot" to mind our own business. You are legally and morally an adult and I respect that. Just want you to be happy even now, especially now.
For the record, I do know of several "first loves" who met at 16, married at 18, had babies at 19 and live happily ever after. Your choice.
