As far as I can tell you, it is far from the truth. Beethoven experienced little but frustration in his relationships with women, partly due to his misplaced sense of his own social rank in the society of the day, and partly because he was beset by financial problems during the earlier years when he might have found what he wanted. Later, his deafness left him feeling deeply isolated from others, and he took out his frustrations by engaging in an acrimonious and costly custody battle over his nephew after his brother's death. It is indicative of Beethoven's attitude that he always felt that his brother had married 'beneath him'. Actually, this was only a kind of aristoctatic snobbery, and the Beethoven family were only very minor and insignificant aristos anyway. Overall, Beethoven doesn't impress as having been at all a happy man. He had to bear the terrible burdens of failed relationships and deafness which led also to public ridicule. He himself wrote that at a certain time, he seriously contemplated suicide, but couldn't do it for the sake of his art. And that was all he had really, his art.
