Okay yeah, that says a lot more. It's possible she regrets sleeping with you, misses her ex more than she wants a serious relationship with you, and/or probably feels like she fucked up the potential friendship she had with you and would rather cut her losses.
It sucks she chose not to tell you this to your face (or what she might actually be feeling), but it's likely something like that, and there's not much you can do about it. Just give her space, maybe she just needs a break from you to figure things out. But don't expect anything.
And I guess if you lent her a lot of money without clear re-payment terms...don't expect that back either.
