Why did otto von bismarck create an alliance with austria-hungary and italy

He created an alliance, for he was I should say 'scared' of the enemy alliance that was formed, the Triple Entente. He wanted to make sure that the other countries around Germany was on their team, and he just wanted allies

However, Italy would later break away from the Triple Alliance and join the Triple Entente

Cis wrong and it is a because i said so yaass

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
