Yes I think it is important to visit him even if he says he doesnt want you there. I try to see my son at the same time every other day while he is in hospital even though he doesnt want to speak to me because i am the one who put him there, but i think it shows you are supporting him , that you love him . Even if he doesnt say it to you after a while he will appreciate it and will look forward to your visits. I bring my son a bottle of Pepsi every time I go so even if he doesnt really care to see me he looks forward to the Pepsi, but you can bring whatever you like , or whatever you think he will really appreciate each time you show up. My visits are very short as he has nothing to say to me but i like to see him so we each get something out of the visit.
