I want a second baby but my bf doesn't 😞

Hi ladies.

My and my boyfriend have a son who's 2 in December. I really want another baby, like badly want another however he doesn't.

I'm not sure if he ever wants another as he's said he doesn't. I really don't know what to do because it's making me so unhappy 😞

I love him so much, but how can I be with him when I desperately want another child and he doesn't 😢
