2nd kid

Recently my partner and I have started talking about planning for the second kid. For background I come from a close knit family of 3 siblings with a single mom. I played with cousins my age during my childhood and still travel to see my grandparents at least yearly. We were on food stamps and my mom often worked 2 jobs. My mom has passed away, the siblings birth years are 1992, 1994, 1997 (me) and 1999. My partner has one sibling they are about 7 years apart, his parents are still together. They were able to rise up from lower class to middle class and he is not close with any of his family. He played with neighbor kids. Now for today, he has wanted one kid, ive wanted a large family but have compromised for 2 given our house size, the state of the world and him not wanting a lot. We had our daughter in '22, he decided we can have another. I started school for a possible remote job, ill be finished in 2-3 years. We decided we will try for another after my schooling. This will give them a nice age gap but still be close enough that they wont be distant. My nephews are pre teens and we have no cousins in our area. The rest of the siblings do not want kids. Now hes talking about how hes not sure he wants a second. When i told him i wasnt sure how i felt about it since i have always wanted a large family, he responded he has always wanted a nice house. He is a welder and makes good money, i currently work part time so i can stay focused on school. I'm not sure how to go about this. Its not like i dont want to work, i want to be the bread winner so he work on his own business. I just cant imagine life as an only child myself and want me daughter to have the type of relationships that i have with my siblings. Thanks for reading
