My 2 cents:
Even though I haven't read this entire thread, I gotta say I'm pretty damn impressed with the overall quality of the advice, thought, and suggestions given and with much good karmic intention, to boot. You should go through all of whats been offered (and I mean every last bit like you were studying for a final) gather what makes the most sense to your gut on a harshly objective level, and really take it to heart. Then make a plan to slowly but consistently put these things into action. And I don't necessarily mean put these things into action totally directed at pursuing women; put things into action directed at making some changes in - and within - you. Ideas are great but where the rubber meets the road is in the implementation of those ideas. And yes, clearly this is the really hard part, but as a rule, nothing much gets accomplished without hard work. The best definition of luck that I know is: the coming together of opportunity and preparation - nuff said.
Now as for a few random points just coming from me; don't feel alone in the world or shitty about yourself because you're having a hard time "getting a girlfriend" as you put it in your original post. I am, and have been for at least 4 years now, in a similar boat. My story leading up to this point has little in common with yours, I'm sure, but I have not been in any sort of relationship at all during that time. Now I haven't exactly been pursuing that like focused fiend, but I have really, really wanted some sort of connection and have been constantly open to becoming involved either casually or something much deeper. The results: I have had maybe 6 "dates" and slept with exactly 3 women and not particularly successfully in each case... in the past 4 or 5 years. Yeah, I am sorta picky but nowhere near THAT picky, LOL!
Granted I'm not very financially endowed, which these days it seems to me, sadly, a huge handicap at least for the first 10 - 15 yards of a 100 yard race (the finish line being having established an ongoing relationship with someone you want to be with). As for other criteria, I have a good family name in my community, I'm intelligent, exceptionally kind and respectful, well educated, a great conversationalist and cook, I'm pretty fit and trim (my avatar is really me and I'm pushing 50 hard), I have always been told that I'm handsome, not infrequently I've had random people both male and female say to me something like "I bet you have more ladies after you than you know what to do with... blah, blah, BLAH.
Without going into the whole, long story, I suffered a number of truly shitty circumstances at regular intervals over 10 or 15 years, at work, in my personal & family life, and in my marriage (now divorced). The result is that this series of events did a real number on my CONFIDENCE. Sure a few of those shitty circumstances were at least partially self-created and that I can accept and deal with, its part of being an adult. Most, however, had nothing to do with my abilities, performance, intentions, actions, etc.
I have always been a good guy, optimistic, friendly, confident in myself, and comfortable with who I am as a person. Now, though, I carry around a slightly shaken confidence sometimes, but I've worked hard on repairing the foundation that cracked inside. Still working at it and making progress, but lemme tell you it doesn't happen overnight. I guess what I'm saying is that I believe, quite strongly, that in situations like "trying to get a girlfriend" the vast majority of people subconsciously project important things like confidence - or lack thereof - no matter how hard they try not to. So you have to approach yourself from the inside out to get at and address the problem you're having. Unless one has the skills of DeNero, it's next to impossible to act through it.
Having said that, though, over the sort haul sometimes it helps to have a serious talk with yourself and come to the conclusion that you really like yourself just fine and you don't GIVE A SHIT about what other people think, see or hear with regard to you. Sometimes it helps a lot to just put a smile on your face, a happy song in your heart, say Fuckem !, and go out and just be yourself and have fun doing it. And for pete's sake, whatever you do don't try too hard when interacting with a woman you find attractive.
Hope I've given you something worthwhile to consider....
