Ok, I need some suggestions on this one. I am going to post a representative scenario. Any input will be appreciated.

I see a cute girl on the train. I walk up and open direct. She is flattered. My vibe can best be described as a mixture of interest and disinterest. Within a couple minutes of convo, she is attracted and starts asking me questions. Given that the final stop is approaching, I have to get her contact info fast. As she is talking, I give the interaction another spike by saying, "god, you are cute". Within 30 sec, somehow something came up and I said, "we are not doing that. What we are going to do us grab a cup of coffee". She said, "maybe".

But then some switch went off in her brain and she said she said she only wanted to meet professionally. I said I don't want that. She said too bad. I left to collect my bag. She exited the train. I reminded myself that I cannot give up so easily. I made another attempt. No dice. I told her jokingly, "you have way more game than me. I try to ask u out and u try to sell me shit". She laughed and we bid each other goodbye.

My question is what are the likely reasons that she felt uncomfortable and flipped her initial stance? To me it seemed like she was definitely interested. What can I do better in such situations to alleviate her concerns?

Was the train packed? I'm no expert but if I'm on a crowded train or bus or whatever, I try to make my attempts to game her way more subtle. She'll appreciate your social intelligence and indirect worked for me when I tried it.

But, if she said "she only wanted to meet professionally" i would have gotten her number anyway and try to convince her otherwise through text and what not. Perhaps she was trying to play hard to get in front of the ppl on the train watching. I would have still got her number "professionally" and tested to see if she was BS'ing later.

what was her profession? If she is in sales, there's a good chance she was flirting to sell you shit.

She could have a boyfriend and was just having fun flirting with a stranger. You'll know for sure if you do meet up with her.

Playmaker, it was not crowded. In fact no one was watching.

Job: she was a financial rep and was asking if I needed one.

Somehow my intuition is that it was a comfort issue. "I'll be a slut if I give him my number" kind of deal. It is just like when u r about to have sex with a woman. She is turned on but afraid of being judged etc.

My feeling is that this may in fact be the situation with many girls. What do u think?

Brutal honesty, i'd say the most likely explanation is she was interested in getting your business. I'd assume it's not pretense. It's one thing if you both keep it ambiguous, but if she said "only professionally" that's her being very clear.

Quite possible that this was the case with this girl. What I was looking for though were general pointers on breaking through resistance borne out of her being afraid of being judged.

Be comfortable with it yourself, and don't be too loud and conspicuous in a public place in the daytime. Other than that, not much you can do. I don't think that's the reason why a lot of women are going to refuse to give you their numbers.

Stop flirting. Be normal. Day game is a test of how normal you can be. Flirting always backfires. Girls rarely trust guys who just start flirting with them out of no where during the day.
