You won't be invisible to the right one. The right one who sees you will discover a treasure, and look around in amazement wondering HOW ON EARTH no one else has not already found you.
Being seemingly invisible should never make us feel less than we actually are, as Christians. As pleasant as it is to be validated by others in some way, we don't need to feed on the validation of others. Knowing that you have worth, no matter how you are wired (and not flaunting it), respectfully engaging all people and trusting that God will guide you through the murky waters of meeting someone, just try to enjoy the company of others in the meantime. Soon enough some guy will catch your eye somewhere. Then he will rush off to the rest room to make sure that his hair is okay before pinching himself to make sure this "dream" is actually happening before summoning the courage (guys get scared too - that bravado "I'm a chick magnet" thing is a myth) to walk across and strike up a conversation.
