When someone says "um," it's often a verbal filler used to indicate hesitation or uncertainty while they think about what to say next. It can signal that the speaker is processing information, gathering their thoughts, or unsure about how to proceed in the conversation. Additionally, it may serve to hold the floor in a conversation, signaling to others that they are not finished speaking yet.
If a guy says that you are pretty it does not mean that he likes you. He could like you, or he could just be paying you a compliment.
