>>1711693>the OneGive up the Oneitis, Anon. Take on an abundance mentality, and work from there. People change over time, so even if you theoretically found your "One", there's no guarantee that 5 years down the line she'd be the same person you fell in love with at the start, in fact, she's statistically guaranteed not to be.
Ideals are fine, if you realize that that's precisely what they are. When the ideal becomes a concrete standard that uncompromisingly must be met, you're going to have a bad time, no matter what that ideal be, whether Christianity, Relationships (Stepford Wives, anyone?), or any other subject.
In the end, there are plenty of women out there, slutty or not, for the taking. You're looking for a woman that reminds you of Ayanami on multiple aspects, it seems, and while there's nothing wrong with that, you have to remember that the woman you'd be seeing is her own person, and not a clone from the Reiquarium.
You do need to mature, frankly speaking. Because you're hooked on the idea of A) a "One" out there that everything just falls into place...Life is not as simple as a Disney movie, it's a lot more complicated than that. B) Finding Rei in the form of Human Flesh. You're not going to. We are the sum of our experiences and interactions with those around us. You will not find a person that has had a mirror-image of Rei's experiences. And C) You've got the age-blinders on. You said yourself that you focus on girls your own age. Nobody ever said you have to. You've got a whole approx 15-year range acceptable to society to browse, if girls younger than you is your fancy.
You've got some growing up to do, and it doesn't involve sleeping with barsluts, unless you desire sexual experience to get better. You're looking for Wife Material. Problem is, you insist she be a mirror-image of your Waifu, and insisting that the temporal match the ideal, bit for bit, will always be a failing endeavor.
