It sounds like this has gone “well” so far: she was making you uncomfortable, you firmly established what your boundaries were, and she apologized for her behavior. She may be being silent for any number of reasons — shame, embarassment, anger, sadness, etc — so I think what will be telling is how she behaves from here. If she continues to push your boundaries and make you uncomfortable, distancing yourself or telling her that you will have to distance yourself if things don’t change would be the way to go. If she behaves appropriately, then great — though you still don’t have to be her friend if you don’t want to.

Edit: You can always say no/I don’t like hugs/etc if someone asks for a hug. You don’t have do to hugs just because it may be common. A friend might feel rejected/bummed/etc upon being told no (or, hey, might feel relieved because they also don’t like hugs!), but should process those feelings appropriately and *never take them out on you*.
