I've setup a date with a HB3.

It went like this:

Me: I can meetup at Thursday for an hour+, does it work out for you?

Her: Hi... Hmm yes

Me: Good, we will go to <...> at <...>

Then she stopped writing any messages.

Later I understood from her that the issue was that I chose a place and time like she doesn't have a part in this.
She thinks it is egoistic.

I don't get it - I tried being assertive and set the place & time without asking the girl, yet she finds it a bad approach.
What's wrong?
