Be patient. She was honest about becoming involved too fast in her previous relationships and was hurt as a result. I believe she likes you and doesn't want to mess things up by rushing. This is a very good sign, if she wasn't interested, she wouldn't waste her time. My advice is to let her know you like her and, respect her enough to give her the time she needs to feel comfortable at the prospect of dating you. Trust me this will work in your favor. She needs reassurance that you are different from the rest.
