My father-in-law recently had a stroke and since moving into our house seems to act as if he still has symptoms of lasting effects from it. Is this common?

My husband's dad had a stroke before Thanksgiving. He was admitted to the hospital and the went in and they stopped the clot. They had him in ICU 4 a week then moved him down to a regular room to start rehab. They then transferred him to an assisted living/rehab. He was making great strides b4they transferred him there. After he was there, he seemed ok BUT when my hubby couldn't spend the night he had tried getting out of bed and fell and got a hematoma on his head. They transferred him back to the hospital & they kept him for a couple of days later. My husband stayed the night. The next day he was going to his therapy & supposedly he fainted when we left & my brother-in-law was there. They sent him to a different hospital all together & we couldn't locate where they sent him. My b-u-l said they wouldn't give him any info as to where they sent him. He said the hospital he went to prior would not let anyone into the ER & could not locate him in their hospital. We finally found out, after many calls, he was transferred to a totally different hospital. They kept him until 4 days b4 Christmas. He seemed to do alright except when home health came out. He would act as though he was seriously, I'll. He has quit eating, keeps us up all night, won't participate in any of the therapy, won't drink anything, & acquired a bad bed sore from the assisted living. Whenever the folks from home health come out, they act as if it's my fault he is in this condition. He WILL NOT let me help AT ALL with any of his care. When I try & do as they have shown me, he totally stiffens up and makes it impossible for me to help. I overheard him tell them on many occasions that I do nothing to help when I do try but he makes it extremely difficult. My hubby keeps telling me to leave him alone because he is dying. I try & cook what he likes but he won't eat it. The bed sore has gotten worse because my hubby won't change the badges like instructed. When I try to go in & change it, I need help because of him stiffening up & my hubby gets mad & starts yelling at me. When I try & do anything to help, I am pushed away. I try and sit with him to keep him company he says he wants me to leave & wants my hubby. He says he can't move his left arm & leg can't move but when he thinks we aren't around or can see him he moves it just fine. I even caught him in the middles if the night out of bed walking over to his dresser. Also, he has fallen out of his bed three times. I say falling but got out of bed himself & yells for my hubby saying he don't know what happened. When this happens there is no sound of him hitting the floor & it happens right after I look in on him. He has told one of the therapists that I rough him up and refuse him food, water, and won't keep him company. None of which is true. I sat with him one night for about 2 hrs while he slept & he told my hubby I lied. Luckily my hubby knew this to be true. I got to say it, but I believe he is taking it. Any ideas or suggestions would be helpful
