Want a baby with BF

So my boyfriend and I just graduated high school together and he recently gave me a promise ring after an early miscarriage. I love him to the moon and back and would do anything for him. I can't help but want to have a baby with him, even though I'm going to school and he's taking a year off to work 600 miles away from me. Is it wrong if I ask him if he wants a baby? I know he'll say know because he doesn't want kids but I want a baba to show our love and a way to be close to him.
