usage of 'vicarious'

[Tan Elaine]

If a woman's children have left her because they cannot get along with her, and her nephew comes to live with her and she treats him strictly, not allowing him to go out when she is at home and places other restrictions on his personal freedom, is 'vicarious' the correct word to describe her behaviour towards her nephew. If it is the correct word, how should I use it?

She is treating her nephew vicariously with her restrictions on him.

I doubt my sentence is correct to convey the meaning intended. If so, is there another way to phrase the sentence with the word to convey the intended meaning. If not, how should I write to describe the matter.

Thanks.

Her behaviour is controlling.

As you will have learnt from a dictionary search, vicariously means something quite different.

Thanks, Rover.

I was just thinking 'vicarious' could be used because her sons have gone abroad and left her. So, since she cannot control her sons, she is controlling her nephew vicariously.

I thought it made sense, but evidently I am wrong.

It does make sense when you put it like that. You are not wrong.
