Judging by the questions you ask, how you ask them and the types of responses you give, I can only deduce that you may not have had a lot of socialising throughout secondary school to uni. That's my guess as to why there are many things about women behaviour that you dont understand.

I think a lot of the women who do that to you "string along" as you see it etc, may have just plainly found you uninteresting after a while.

The solution here is honestly quite simple. Just get more interesting. how do you do that? work on improving yourself, find a new personality. People like to think "i am born this way" and all that nonsense. it's a whole lot of bullcrap. If u dont like who u are today, change it. if u think who u are is not interesting to the types of girls u want, then change urself. grow. learn to find a new character and personality to be.

If u cant do that, then change the types of girls u want.
