Whats your reply usually when she texts? "Sounds good, good night." ?
I wouldnt reply with anything.
I'd plan on picking her up when I told her I would. I would also go dead silent and see if she reaches out. If she did not, I would probably flake because at the end of the day she didnt confirm, didnt reach out and is showing low interest. So if she showed up after no further communication, she would show up alone.
Ive actually done this several times. Once I never heard back from the chick so I assume she didnt show up. The other times I got a text "I am here....are you on your way?"....to which I said "Sorry, I never heard back from you and totally forgot".
Flaking on women isnt the worst thing that can happen. More often than not it intensifies their interest if they sort of asked for it....meaning you werent chasing her and didnt care if you showed up or not.
But thats what I would do, but understand I would do that with the attitude of "I dont care if I hear back from her or not". And I truly wouldnt care.
Any woman with high interest will reach out to you. Thats a fact.
Dont reach out to her and you are going to either get one of two texts the day of or the day before the date:
"Sorry but I am not going to make it"
"Hey...havent heard from you....still good for tomorrow night?"
So sit back and see what she does. Remain still and calm. You hit the ball over the net, if she doesnt hit it back over, go find someone else to play with.
