I am sorry Charlie boy is so upset. You can change Charlies opinion of your husband simply by letting him (husband) feed him.
To a cat....food is love and they CAN be bribed. Since he is scared of your husband YOU o with him to feed first.
Have him sit down next to you and hold out food CHARLIE LOVES and will work for. I usually use tuna.
Have him look at Charlie and do a slow blink. That says I like you and mean you no harm.
Even if Charlie will not come to him, make sure he sees that your husband put the food down. do this for 3 days. THEN ONLY your husband is to feed Charlie with YOU not in the room.He should not try to pet or grab Charlie until the cat comes to him on his own.
After about a week Charlie will come to depend on your husband for his meals.He should then warm up to him.
Please let me know how things are going.
