Ftm No more babies

So I know I'm probably just throwing myself a pitty party so ignore me, kinda just need to rant but advice would be nice too. So my hubby and I always agreed on two babies, we wanted to have a chance at both a boy and a girl. We got our little girl 9 months ago and she was seriously such a good baby. She only cried when hungry or wet, hit all of her milestones on time or early. Rarely fusses. Already on sippy cups. Great sleeper from day one. She's amazing to say the least. But ever since we had her hubby has been saying "no more" saying "we got too lucky the next one will be hell" and pretty much said she's going to be our only kid. It breaks my heart.. I love being a mommy.. I loved pregnancy. I love it all so much.. I wish he would have decided this before we had a baby bc I would have enjoyed pregnancy more, the infant stages more, just generally everything much more:( I'm so sad and I've been seeing my little one interact with other littles lately and it makes my heart happy and sad at the same time bc I know she'll never have a baby sister or brother:(

Edit bc I forgot to mention it: he is planning on getting a vasectomy very soon within the next month
