I came on way too strong with a girl. What do I do now?

I met a girl I REALLY liked. I mean I liked talking with her so much that physical attraction was an afterthought. The first night we met at work, we talked for over 3 hours straight, she even stayed after her shift ended to keep talking with me. However I wasn't going to be working there that often, so the next time we saw each other, at the end of the night, I told her "Hey I know this is forward, but I don't know when the next time I'm going to work here is, and I really like you, so can I have your number?". She kinda giggled and said sure, and gave me it. From there I had already come on super strong, asking a girl that fast, but then I made it worse. I texted her that night, she ghosted. I called her 2 days later, asking her out. She responded, however said she was busy. Then I officially seemed to kill it, I texted her a day later asking her basically when the next time she wouldn't be busy was. She never answered this text. I waited about 2 weeks then called her, she didn't answer, I left a message asking to talk, no call back. I still really like this girl, and I think she at least somewhat liked me in the beginning, and I will be going back to work there soon. Is there a way to salvage this? What should I do?
