I suspect the main cause is a lot of people are not happy in their marriage, or have bad memories of their past marriage(s). LOL.
Seems rather out of context to me, but who am I to judge. Kosulin, care to elaborate on what you meant?
My guess is because he was a composer using the classical style in the Romantic era. Classical composers wrote for the mind more than the heart.
Schubert did have a way to make that work for him. I think all music is written reflecting personal feelings to an extent, but it can be a lot more subtle in things like late Mozart, who often used chromatic chords and frequent modulations to take out a breath. Beethoven is a more obvious use of using the classical mold to show personal frustration. Romantic composers simply changed the way this personal expression was carried out.
Sorry for the dumb questions, I'm not really good at music history, but was Schubert technically classical or romantic?
