Is this Honestly A Deal Breaker?

Hey everyone I am just looking for and opinion her and please kind words would be welcome and nothing rude about my boyfriend. Ok so we were talking today and he said how he doesn't want children well I do someday and when I asked him if he may change his mind in the future he said maybe but not for a couple years. Is him not wanting children a deal breaker??? I think he has fear because he was born sickly and not expected to survive. Though I Love him so much we have been together for almost 8 years and things are not always easy but there not bad either idk what to y'all think
