Have I been used by this girl?

Basicly, I had with a girl last summer, I really liked her but I ruined it by getting bk with another girl( who I loved) but iv been single for months on end now, the girl I had with last summer started taking to me n stuff n she slept latly and u can guess what happend, I really thought something was guna start between us. She's god damn beautiful but she hasn't talked to me since she left in the morning, without a word after she left... I duno what to do, it wasn't just a one night stand felt like more, so do u think there's a reason she's not talking? Or have I been used, any answers ladies n gents?
