...Never heard of you in my life.
But, to make it feel better for you.
There's the type of person (...*ahem*, LUKE SKYWALKER *oh look! a bird!*), that will over analyze how she became uninterested, and STILL miss what the reason was. These types of people will never find anyone of worth, because they can't see though the air to the end of their nose.
Then there's the type of person that'll open the same way, talk the same way, and act the same way. Robotic in nature persay? We tend to suggest this type of person has no fvcking idea what they are doing.
And then there's the type of person that kinda knows what's going on. He can make the girl laugh, be interested, close her, whatever. He is almost there.
But there is here, and here is when you realize, fvck the woman. Being a supplement to life is a lot more beneficial then having to rely on a shaky foundation (whether it's her or YOU).
Number 1. Sort and take care of yourself. If you can't take care of yourself to every degree of comfort you require, you WILL have a relationship problem later in life.
Number 2. Hold a high standard. Nothing is wrong with meeting and enjoying the company of many women while you are looking. It's more of a chance to discover the small percentage of women that are high quality to you.
And Number 3. Learn some fvcking pick up skills. If you can't attract a horse (or a train or bus..), even if you find high quality, you won't be able to have it. Remember that. It's your reason for being here. Let me say that again. IF YOU CAN FIND WHAT YOU'RE LOOKING FOR, BUT YOU CAN'T GET AHOLD OF IT, THEN YOU HAVE A PROBLEM.
A big fvcking problem. Why? Because you did something WRONG (no, it's not her fault for not liking you). Natural attraction is what it is, natural. If you act UNNATURAL in one or more of many ways (robotic, unconfident, indecisive, unattractive, not showing some attraction to her, etc), she will pick up on it in exactly the manner you choose what to go after.
Thus, let me re-emphasize the point here. On the pickup (requires some skill), to even have a chance at what you want, you HAVE TO ACT NATURAL. If you run into high quality, you better be high quality back, because quality DOES NOT SETTLE FOR LESS THEN EXPECTATION!
