Well, before I got married a couple years ago my friends always used to bug me that I was "relationship guy". I had my share of meaningless one night stands and stuff but for whatever reason women always wanted to be my "girlfriend". In fact my wife was warned not to go out with me by one of my good friends. He told her that she would "fall in love with me" to which she scoffed, "yeah right!"
Anyhow, in my experience of applying all the different theories and ideas that drift around this place I can tell you this...
When it comes to building a relationship and getting women to look at you like relationship/marriage material then you have to play the game differently. In some ways almost opposite.
All the "get laid quick" and player stuff that you learn around here is counterproductive to any relationship you are trying to build. Chicks aren't totally oblivious. They'll play along maybe to get laid themselves but they won't take you too seriously.
If you really want a relationship start paying attention to the Doc Love stuff. I know he gets a bad rap from some people but that is because his stuff IS geared towards relationships.
Eg. Most guys go in for the kill way too early. They want to get laid or at least some action right away. Doc Love tells you no contact, no kissing, no talk of relationships, no nothing for the first 3 dates! You spend all that time just qualifying her and showing her how much of a challenge you are. I can tell you from personal experience that if you really want a relationship, it works like a charm. It's almost scary sometimes!
My plan for the first 2 or 3 dates was to show chicks the best possible time without any inkling that I was interested in them sexually at all. We'd have tons of great conversation, laughs, and fun suggestive flirting. However when it came time to end the date I'd do it quickly and disappear in a flash. I'd tell them I had a great time and "maybe" we'll hang out again sometime. By the time we did get around to anything physical she would be dying for it! After the deed was done they would all tell me stuff like, "I didn't even think you liked me" or "You never even tried to kiss me".
The thing is that most chicks are expecting a guy to make a move too early. If he doesn't then she's expecting him to ask something about "where the relationship is going" or something that implies that there is some sort of expectation just because you had a date. As a single girl looking for something more than just sex all this must become pretty lame. I think a lot of guys should take a cooking lesson. You gotta let pot simmer a while.....
So don't beat yourself up too much TM. You have all the skills there. Maybe some fine tuning to develop some other aspects of your game is all that is needed.
