This is over msn. How should I turn this conversation around? I think girl thought I meant she is dumb, and resulted in no response back.

Her: So you're planning to open your own psychology clinic?
Her: I'm gonna come everyday.
Me: And what are we going to do? [trying to make it sexual]
Her: Get into my head.
Me: That shouldn't be too hard.
her: 30 seconds pause
Me: right?

end of convo. she didn't respond.

So I like to know what happened, and what I could have said to hook on to what was going on (whether she thought I said she was dumb so stopped responding cause she felt I was a jerk, or if she caught on to the sexual intent of that statement)

Thanks in advance for the insights!
