I think it's about when you first meet a person and feel so deeply about them without any real reason. It sounds like they talked, were intimate, but she doesn't know if she took it too seriously. "I was yours right?" is like she's asking this relationship wasn't just something I blew up, was it? We were together, right, even if it wasn't made official? Then they just fell apart without any words or warning. She fell apart.
