Dating question concerning whether or not I should tell her how I feel?

I’ve known this girl since about mid February, and since then I’ve had stuff to look forward to. We hang about twice a week doing different things (Such as walking on our cities trail system on the river, or hanging out at coffee shops, going to see a movie, or just driving around for 2 hours after a concert.)
I am very attracted to her, there is just one show stopping thing. Towards the beginning, she was very upfront about not wanting a relationship because she just got out of one, and wants to be single for a while. That was about a month ago when she said this.
My question is, should I tell her how I feel and see what happens, or should I just continue as I am? The last thing I want to happen if I tell her is it changes out relationship for the worse, because I really do like where it is right now, even if it is just being friends.
