Andrew not only had to work

[Bassim]

I am wondering if my sentence is grammatically correct.

Andrew not only had to work in a restaurant, but also had to take care of his old mother, who he did not want to put in a care home.

Instead of "care home", I would use, e.g., "nursing home" or "home for the elderly".

 

[tedmc]

Last part: should that be "who" or "whom"?

teechar,
Can i use "have" instead of "had"?

Andrew not only had to work in a restaurant, but he also had to take care of his old mother [STRIKE],[/STRIKE] who he did not want to put in a care home.

Care home is fine and no need for a comma after mother.

You can't use "have" but you could use "has" in place of "had" both times. You would need to change "did" to "does" at the end.

I am wondering if "he" after "but" is compulsory or the sentence could be grammatically correct without it?

The sentence is incorrect without it.
