Where do you see her and how exactly are you going to flirt without approaching her?
It sounds like you're trying to find a way to make her desire you without any possibility of risk, rejection, or embarrassment on your part.
Why can't you approach her? Why do you even like her? I'm guessing you barely know her.
It's only weird because you feel weird about it.
You have something like making eye contact, smiles, etc. as non-verbal game and see how she reacts to it.
This can give a first indication if a person likes you or not and if she is approachable.
I see her on train station, sometimes I pass her when she is waiting, sometime im early and she isn't there yet.
Also on the way back I take the same door to leave the train as she does. We both hurry to make it to the other side or another train will cross and you have to wait 5 min.
After that she unlocks her bike in like 10 sec and is gone.
I'm curious about other people view and if it is weird thing to do after 3 months seeing her. I like the shape of her face , her eyes,nose,month combined together, the tone of her voice. I know this is just a start, thats why I want to get to know her, but for that I need to make sure she wants that which got me to the question if that is weird after 3 months.
Don't even think about engaging 'til you reach an (at least) 2 week streak, private.
Otherwise, how do you spect to attract her if you lack the masculine hormones that will draw her attention? And even if she rejects you, you won't feel as bad as you'd feel now if she did, trust me.
Yea I reached a 2 week streak serval times.
she knows you for 3 months, she knows your behavior, what are your reactions and interactions and suddenly you start to behave differently. That is totally inconsistent and it will be weird. She will think: What is he doing? Why did he wait so long if he was interested? Was he scared before to go for what he wants? What did change? Did he just read some pickup?
Key thing to remember is that attraction diminishes with time (if no action is taken). 3 months is very long time particularly when you see her 2-3 times a week. If she is not extremely needy she moved you either to friends category or category "afraid to go for what he wants". Both are unattractive for women in terms of developing it further.
And flirting is the seductive part. You can only use flirting if there is prior strong attraction. Flirting with somebody who is not attracted to you is just creepy. And there we are again - attraction diminishes with time.
I would recommend to not see her for 3 months, work on yourself, practice having fun with other people men/women (because you want to have fun in your life), and when you will see her again after 3 months she will be like wow, he changed, there will be innitial attraction again and she will again need to sort you into some category. And since there is attraction, you showed that you are man who goes for what he wants (her) --> flirting, she can sort you this time into boyfriend category without any weirdness.
Thanks for your view. I don't agree with your 3rd paragraph. Flirting can be used ot see if there is attraction between people. But yea it might be see as creepy.
Not seeing her for 3 months is no option. I see her atleast 1 time a day as I get to the train. Also in 3 months she is gone.
