How do I break this off and still keep her around as a friend? if I were to just tell her 'lets just be friends' she will take it the wrong way.

I've met her online, after a few texts throughout the week we've set up to go for a coffee. Instead I took her to a lounge on the way to a coffee (away from her comfort zone), we had a drink made out and went to her place and had sex.

I had stayed the night over for some more morning sex (yes I know terrible me), she then started saying how she never does this sort of thing and that I am something quite the extrodinary. She then continued saying tat she has a really good feeling about me and sees herself with me to which I had said "we'll see I have no expectations"

I then left and she had been texting me non stop, the girl is a lawyer and in her late 20s id imagine she has a social life and work to do and not rape my phone with texts every 5 minutes.

Today she is texting me and telling me she is falling for me and falling inlove, where Ive literally said nothing or even hinted i still want to be with her.

How do I slip away without wrecking her emotions too much?
