I can't speak for your father of course, but I do think he likely had a valid concern that he may not have effectively communicated that all of this time with the computer was directly at the expense of time spent with the family. He may have felt hurt that you seemed to prefer the company of a machine to his and the rest of your family. He and you may also have very different conceptions of what a successful/happy life might look like. I'm not saying he's right, but from the outside I can imagine why he might not have felt supportive and also why you might feel resentful for the lack of support.

Have you directly asked him why he wasn't supportive? Have you been open to his perspective or just assume that you're right and he's wrong? It's easy for us programmer types to try and simulate the mind states of others to avoid difficult conversations (speaking for myself of course).
