I don't think you should be worried necessarily though I can see why her profile statement would concern you. I would be a little disheartened too but keep in mind that romance often just happens whether someone is looking for it or not.

In my own life there have been multiple occasions where I've told myself that I'd like to remain single and then a month later I'll start to develop feelings for someone new just because I couldn't help it. When someone says they are not looking for love it doesn't mean that it can't happen. You can still meet the right person even if you're not looking for them, those romantic feelings can take over and then all that "I'm not looking for love" stuff goes out the window.

All I'm saying is don't give up just yet. Have you told her how you feel?
