How can I track my husband phone

You'd have to able to login with your husband's Apple ID and password at icloud.com . From there you can use the Find My page to see where that phone is (within several feet).

No, we cannot help you do this. It would be illegal for anyone here to try and hack into your husband's account, or even help you do it.

The right way is to ask your husband to add you to share Find My to allow you to track him. He would open Settings, tap on his name, then Find My and turn on Sharing. If you know his Apple ID and password you can use that at https://icloud.com/find.

Any other way is not possible and illegal in most places.
