When someone tells you "see ya later" or "bye for now," it means that they are saying goodbye, but with the intention of seeing or talking to you again in the future. These phrases are friendly and informal ways of parting with someone temporarily.
The person is expressing that they expect to cross paths with you again, whether it's in a short period or an unspecified time in the future. It indicates a positive and casual farewell, suggesting that the separation is not permanent and that you can anticipate meeting again on some occasion.
It's a common way of saying goodbye among friends, acquaintances, or colleagues when they expect to see each other again soon, but without setting a specific time or date for the next meeting. Essentially, it leaves the possibility open for future interactions.
