She needs time?

Hi! I am so confused and I hoped somehow you could help me.. There is a girl, it's been, like, a month now that I know her.. We met at coffee bar where she works and everything was great until last two days. We both had been recently in relationships and anyway "had a deal" to just hang out and have fun, so.."anything could happen.." Well, we talked few times, and even more via mobile phone..twice went for a walk with her dog, once she came to my place and met some of my friends (but she is so shy, wouldn't even come to the kitchen where they were), once came to my place..alone.. etc. you know how it ends. (That day she told me multiple times she likes me really much). Another day I came to coffee bar, she kissed me there, in front of her friends.? Did I mentioned, she introduced me to her friends before also.. And after that, like she got scared of something, I have no idea. I told her, I don't want a relationship, just like her, and she liked the idea.. Now she says she needs time to "recover" from that past relationship and break up she had and she wants time just for her. Did I do something? Or it could be just a phase. But if too much time passes, she could forget me?. Because she goes "crazy" when I am around, and she is different when she writes messages.. I have no idea, if you could tell me something. I don't want to give up on her because I really liked her so..

Thank you for reply.. She doesn't want to go anywhere.. That's what she said " I need some time for myself..I don't have time for us to hang out..It's like walking a dog, work, walking a dog, eating and sleeping".. I told her, we could take her dog for a walk together,or I could "babysit" her but..No...
