girlies please help

i really like this boy and we’ve been talk a lot recently. however, we will be in a really good place and then suddenly we will drift and it gets tiring and boring after awhile. i tried telling him this and he said that he doesn’t want to stop talking, “i love close we are and i don’t want anything to happen that might distance ourselves from one another.” - from him. since then we have been GREAT, like i’ve been so happy but I AM SCARED we will drift again...idk i just need some advice 😅
