That person you seek is out there, she just hasn't found you yet. Don't give up hope, just live your life to the fullest and do what makes you happy. sooner or later you may cross paths as life is funny like that and it will probably be in the most unexpected place.

It's always best to be up front though, if you read around the forum you'll see that a lot of the girls have been married for years upon years before they told their SO and it had the potential to be disastrous. You will skip that step doing it the way you are doing it.
