what happened when zeus got europa

It is said that Europa woke from a dream and summoned the rest of her ladies to take a walk and gather flowers. Zeus, captivated by Europa's beauty, turned himself into a beautiful white bull and approached the ladies, who all ran to greet him. It was then that Europa is said to have climbed upon his back, was subsequently taken, raped, and later abandoned. Mythological gods are often depicted as taking the shape of an animal when raping young women.

She wasn't left alone after the rape, they married later and Europa bore children, I never heard of Zeus leaving Europa alone.
