Imagine I made a mistake so i was the reason that my friend get lost. Is this sentence correct?

I made her get lost.

shininggirlI made her get lost.

No. This doesn't work. Say something more like the following:

I was the reason my friend got lost.
My friend got lost, and I was the cause of it.
My friend got lost because of a mistake I made.

Thanks a lot.

So we can similarly say:

I caused my friend to get lost.


shininggirlI caused my friend to get lost.

That sounds too planned, too 'on purpose'.

If you don't mean that, you don't want this sentence.
