How can I make uncle love me more?

You mainly want to find out whether your uncle loves you or not. If you are sure that your uncle loves you, then you can talk to him more in peacetime. Some boys don't like being too ambiguous with girls, but that doesn't mean they don't love you. Lovers who love each other should keep a certain distance, so that they can come back to you for a longer time. So do girls. When a boy listens to you, everything depends on you to be nice to you.
