I appreciate the thoughtful responses and any additional input would be appreciated. I know my original post was a little lengthy but it is very important for me as I am trying to have a dad...

I feel that if I do not help him realize things (our relationship has really improved) then he will be doomed and get a heart attack in a few years (he is turning 50 in July). Time flies....and I understand the poster's issue about the money issue but it really has nothing to do with that and has to do with me wanting my father to be happy and enjoy his life. I know he is living in misery right now and to get away from his outer protective shield is difficult.

Saying all that...he has been very nice lately and I am starting to feel there are some things different as he wants to have a relationship with my little brother and I. I have a very good heart and I myself have improved my OCD by 70-80% and feel very good about myself and my future. It is difficult to have someone who is 50 and Persian who has OCPD to be able to accept that they are not perfect and until they realize that the change is difficult. We will see what happens but any other input would be appreciated. Thanks!
