It's possible. I had been going to cons since 1978, and I met the girl who would be my wife at a vcon, and we've been married 21+years.
GOOD THINGS CAN HAPPEN.
"RIGHT" THINGS HAPPEN.
WONDERFUL THINGS CAN HAPPEN.
One thing I can recommend - know your spiritual beliefs. Whatever they are, examine yourself and see why your beliefs stand on solid ground.
Next: Find a social circle or regular meeting that meets that spiritual intensity. This does not mean going all orthodox, just meeting your own level. There are many sorts of clubs or groups that match on spiritual intensity, from Yoga classes, to environmentalist meet ups, and 100s of churches and religions.
Be sure of where you stand and why.
THEN (although many have done otherwise,) DO NOT date OUTSIDE of that cosmology. You will be happiest if you find a "fellow traveler," and you can do that best once you know in your own heart where you are going and why.
The next trick is to find someone going your direction AT THE SAME SPEED as you are. That way you won't be growing apart 25 or 35 years hence.
Lastly, you and she have to become BEST FRIENDS. As in, closer and more important than your own family. The person you go to with your most troubling inner struggle is HER, not "the guys." Similarly, she tells her most intimate troubles to YOU - not at "girls night out."
That's all I have...
