Really good topic because it has been on my mind for a while...
I know EXACTLY how you feel. The answer isn't so black and white though... let me explain how things have gone for me and hopefully it gives some insight.
When you get "good" and acquire the abundance mentality that you may have read about around here, then yes, to an extent you become a little bit more numb to those crazy feelings initially. BUT, read on, this isn't a bad thing.
Before I had any success with this, I may have been like you, if I met a girl, ANY girl, I'd thank my lucky stars and if I saw her once or twice I'd begin to feel all those amazing feelings of how special she was, how amazing she was and how I thought I was falling head over heels for the girl. But those relationships came and went. I'd be crushed when they ended and never knew where I'd meet another girl ever again, let alone a girl as
amazing as her.
The trouble was though... some of my earlier girlfriends, some were nice, some were not, some were downright abusive. But no matter what, I had no other options and it made me feel things I shouldn't have for girls I really could have done better than because I had no other options, girls who would like me were scarce. Years later I look back and can't even see what I was thinking ever dating some of the girls I did when I was a kid.
In the last year, since I jumped right on board with this website, my success with woman has gone way up. And you are totally right... you meet girls, girls even better than you have before and those amazing feelings just aren't there. Sucks right? Well... no... keep reading
The thing is... when I meet girls now, I don't end up falling head over heels immediately. I have learned to spot signs that she may not be right as girlfriend material. Signs that she's not what I'm looking for and be willing to pass up getting serious or even getting with them at all if I just don't feel it. I can do this because THERE WILL ALWAYS BE MORE GIRLS TO MEET OUT THERE. And you have to get to a point where you really believe that. This leads to a little discussed phenomenon where you are now consistently meeting new women and just as you said... you start to feel like you'll never meet another one who will sweep you off your feet. Girls are just girls and there'll always be another... you're not getting those special feelings anymore. But that means this is WORKING! I know... believe me... at first, this can get you down... it's almost like you're becoming numb to it all and it kinda sucks. If you can keep meeting and dating new girls, how will you ever get to a point where one stands out and you don't just feel like you can always find BETTER?
Well... there is good news. We're all human, if you are open to meeting that special girl and you do find her, you'll know. Those feelings will come flooding back. It will just be more rare of an occurrence. I say this is good news though because you only get these feelings when she REALLY IS special. I got those feelings years ago for girls I should have known were no good for me. I could have done so much better. Now when I get those feelings it really and truly is only when I meet a girl who DOES stand out and DOES meet all the things I like in a woman. But there is a totally different dynamic now. I don't get these feelings for just ANY girl who seemed to like me... I CHOOSE the girl because I can meet other girls, I know I can, but THIS one finally stands out of the crowd and I want to pursue her.
The girls I felt these things for before were 5's, 6's, 7's but the girls now are true 10's.
So that's my story. To be honest, I'm not a die-hard "everything happens because it's meant to happen" sort of guy. I believe love can happen but I believe TRUE love and lasting relationships come when both parties choose each other out of actual love, affection, attraction and respect and not out of other things like loneliness, neediness or other negative emotions. I don't believe in a "One". There are many "One"'s out there. If things don't work out with one girl, there will always be more for you to meet. But I also believe this is a healthy attitude because you stop being in a position where you NEED a girl and end up in a position where, if and when you decide to maker her your girlfriend, you are doing so knowing you could have other girls but you CHOOSE to be with her, and it will make for a much healthier relationship all-round.
I say all this because I admit... for months now, I've been meeting so many new women, and just haven't felt those feelings until what do you know... I met a girl lately who has made all those feelings come back. The difference now though is... I HOPE things continue to go well with her but I'm no longer coming at it from a needy point of view. If it doesn't work out, it doesn't work out and I know there's more out there. If it DOES, then I know I chose her when I could have had another.
Just my personal take on it, but I hope it helps.
