Husband is already talking about vasectomy.

We are due in December with our second. Since we'll have a girl and boy then, he has basically just said that he's done having kids. And he gets all bewildered when I am even the slightest bit offended that he's reached that decision on his own. Don't I get a say??  
He's mentioned "getting snipped" several times and talked about a potential reversal if he were to change his mind, like its the easiest thing in the world. 🙄 
Hello, it's my body and they're my babies too! 
I would love to get some thoughts on this.
