Did Henry VIII every want to marry Mary Boleyn?

No more than likely he did not. He may have loved her (or thought he did) and he even may have had fun with her in bed, but more than likely he did not want to marry her. For one she was already married when they started their affair. The second she was not exactly a good choice for Queen. She had been around while she was at the French court sleeping around with lots of men Francois I called her a weirdo and more infamous than anybody.
