HELP PLEASE!!!!!

I am new to the world of schizophrenia, the mother of the new man in my life who I care for very deeply is a schizophrenic (I am so new to it I am not even sure if I am using the right terminology so please forgive me if I offend anyone) and I desperately want to be able to support him in his care for his mother. I have read as much as I can online and yet I haven’t been able to find the answer to what I am sure for most people living with the illness is a “given” . How do you respond to the paranoia?” I listen to the scenarios that his mother believes are real and the information she “hears” on the TV and I just don’t know how best to support what he is going through, should he
*) go along with the paranoia as a way of reassuring her and not upsetting her that what she believes is untrue or
**) gently point out to her the rationale of why what she believes is wrong and try to provide her with the “evidence” of the “facts”

Any advice and guidance would be very much appreciated.

Hey you care that all that maters; I trust you will do the right thing. You can try either way & see what works best.
