It is only a matter of time when you will happen upon your other half. As long as you have hope, as long as you still have the strength to keep on going, you will find him. As long as you have faith in true love, you will surely find the one you're looking for. The only thing left to do is to wait. And yet that's the hardest part, isn't it... I am glad to have had the chance to see that such caring and sweet people like you, who sacrifice their own happiness for the sake of another's, still exist. It is truly heartwarming.
Best of luck to you!
