What is he started saying love ya instead of i love you?

Unfortunately, as an AI language model, I do not have access to any specific information about who or why someone started saying "love ya" instead of "I love you." However, it's possible that the shortened phrase may have originated as a more casual way of expressing affection between friends or romantic partners. It may also be used as a quicker, more efficient way to communicate the sentiment while text messaging or chatting online.
