Husband doesn't want more kids

I am so upset right now. I know it sounds so selfish considering I'm still pregnant with our second (daughter is 5 and this one is a boy) but our husband just said he's done at 2. It's not like I'm already considering a rhird but I do eventually want one. And all I asked was that we just wait and see how things go with 2 and he's not having it. Won't even consider it. Like my heart hurts because all I've ever wanted was a big family. Like if we only ever wound up with 2 that's fine but to just shut the door on anymore children completely.... that's not what I want. Soon sarcastically said "well then I might as well just get my tubes tied" and he said "honestly it wouldn't be a bad idea" we've always said that we'd never ask one another to do something like that. Maybe it's just the hormones flavoring but now I feel like these next few months will be so much harder because I know I'll never get to experience it again.
