I (24F) dont want kids my partner (29M) does.

I just wanted to get your thoughts on our situation. My boyfriend and i have been together for 6 years (since i we were in college). Yesterday we had a talk on what we want for the future and where we see each other in next couple of years. Well we got to talk about wanting to live together after saving, Where we want to live, buying a car, getting married. All was good until i asked about kids, turns out he wants kids and i dont. I have said before that a part of me feels like i dont want to have kids (no disrespect to those who decided to be parents) because its tough raising someone and making sure that their well provided. My boyfriend on the other hand wants one. He said he wants to be a father and has used teaching his brother to walk as an example of fatherhood. I said that what he did was great (he took care of his brother but that was while he was a toddler) but it was far from what parenting is. He said we will learn when it happens and i just said that while you learn once you become a parent its not that easy and you cant just wing it. He said he understood. We got quiet and he asked what does that mean for us. I said that i think we wont have a future. He suddenly got sad and said he does not want to break up and right now since he isnt earning much hes not thinking about kids and how things might change in the future. Im just confused as i dont want to waste time in a relationship with no future but at the same time i dont want to break up. Is there a way to salvage this? Should we have another serious talk?
