Sasya's decision to leave was completely JUSTIFIED. Mind you even when Karel and he were together he was already depressed and the only thing that was holding him together was Karel himself. Yes it was mostly because of the incident with his boss but i also think it was because he couldn't achieve his dream of being a ballet dancer.
He wasn't content with his life but for Karel he endured it. What could he have done if his lover got imprisoned for 25 YEARS? Stay at the house? Completely isolated?With his mental state? And even if he lived with Karel's brother (which would prevent him from achieving his dreams) we can see how many times he tried to end his life there as stated in the story.
