Go by what's actually happening in the present, and base your decisions on that. In the present, she is not contacting you and has blocked you. So, in the present, she doesn't want anything to do with you.
No one can predict whether or not she will contact you in the future but it's doesn't matter because you don't live in the future, so don't waste your time pondering over what ifs.
Assume that it's over and move on. With time it will be less of an issue and meeting other girls/ seeing friends/ doing other things you enjoy is how you take the sting out of this. If, after this, she does reach out, believe me you will be in a better place to know how to interact with her, if you even want to at that point.
