@lurk3r I totally understand your situation. I know its really frustrating when during dates , women don't reciprocate in a way you desire.
I actually met this girl online and had a date last month , and she came wearing a hoodie and beanie
It really hard to flirt with these kind of girls who show no interest in communicating and seems like only guys have to do all the work.
What I have found out is meeting online girls is kind of waste of time, even though I have had some sort of success in past year( had like 10 girls , with minimum effort). I was also like you , looking online and was once overthinking what should i write to them etc. I realized that online girls have some sort of agenda in their mind and depending on their age,education, English level , they already know what they are looking for. So it doesn't even matter what i say as opening line , some girls will agree to meet and engage in coitus and some will not reply no matter how much you go through their profile and try to understand them as a person.
They also seem to be affected by Cinderella complex.
And then , due to availability of vast number of attractive guys at their fingertip , unless you are really good looking (Which I am not) , they will always go for them.
What i am trying to tell you here is that its not your fault if they don't seem engaging with Online girls, just have a good time on a date , try to enjoy the meal with a person and then at the end find a place and escalate. These girls act quite different when they are alone with you.
I went to LH with that hoodie wearing girl (SNL) even though she could not be more uninterested in me while we were having dinner. As I said , in their mind they already know how much they are willing to put out and its our duty to lead them.
just bite the bullet and go for it at the end of date.
