When a girl hugs you tight, what does that mean?

Anonymous
I was at a party with this girl, and when we were all leaving she came up to give me a hug, but she all of a sudden starting hugging me really tight like she wasn't going to let go. And earlier in the evening she sat down next to me, then got up, stood next to me and was brushing up against my arm for no reason at all. I've asked this girl out, but she isn't ready to date because of a recent bad relationship, and she has a little baby. I've told her that I like her, but she doesn't want to tell me how she feels, yet she flirts with me, and hugs me like I described, not to mention the weird (but awesome) physical contact.

So does she like me? If so, then why won't she tell me?

The reason I ask about this hug is because it's the most obvious hint that she may like me. There are other things, like flirting/compliments. Recently I noticed that on Facebook, she started adding a lot of my friends...now we have like 13 mutual friends
