That’s a fairly common expression, but it needs a context. What did she get passed you? How? It can mean to to pull one over on someone or take advantage of someone but without context it’s impossible to speculate what the problem is. And it could be the wrong expression for your situation.

Hey there! I'll try to help you here. I should think that your sentence sounds a bit awkward as it might be like this: "She got past me" = in this case, the expression 'get past' equals to 'pass ahead of someone or something that is moving (or that is in the way)'.

To get passed someone means to go beyond them, usually when they are trying to prevent you doing so. For example, in football an attacker gets passed a defender. Likewise, during a goal the ball gets passed the goalkeeper.

She got past me? I tried to stop her leaving the building by standing in her way, but she got past me and left by the front entrance. As she went, she obviously passed me in the hall.
