At a loss in my relationship

I hope I'm posting this to the right forum. I rather not talk about any of this in my personal life, I've seen what talking can do. So when I was told about this app, especially the anonymity, I was relieved with having somewhere to share other than google, so...

We've been together for four years in June. I'm almost 25 he's almost 29. There's so much to our love story and I'll tell if you need more details, however I'll just hit the main points. Sorry if this post is so long in advance.

He's hell bent on having a baby and the situation isn't right just yet. I want to wait for 12 more months, next May. I'm done with college in December and I want to at least be not pregnant and showing for my graduation next May. Also with all that time in between I can have a job and start generating income so he won't have to take all the expense burden on by himself. He wants the baby as soon as possible but I can't contribute financially because of my full course load. (There's more to that too, just ask). He won't see the reality and logic in anything all he can hear is "I want to be a daddy, I want to be daddy!!!" And he keeps telling me how patient he was for 4 years and and how he just wants a family with me yet... he didn't have anything together the past four years. Are we supposed to live on the street or separately with a baby and no money?? I just found out he bought a house for us and is renovating it, and I accidently found out sadly and in the worst way (ask about it) he was going to propose for our 4th anniversary. Now he just absolutely can't wait for a measly 12 months. When all I'm trying to do make sure I can give us a good running start. I don't want us to struggle. We're finally at the finish line...why can't he just wait to cross it? I guess after 2 hours of battling it finally sunk in that if he wants it his way he's going to have to take on a lot of financial burden for quite some time. He realizes he can't afford that and got sad. He sounded like he was defeated. He admitted his idea was a bad idea and he just kept saying that. Am I wrong here? Is there a way around all this? I don't know what to do... 😢
