My wife hates me for not wanting another kid.

I'm a young father (only 21) of 2 girls. My wife is now on birth control and has the 3 year rod in her arm but she won't stop harassing me about a third kid even though our youngest is only 3 months old. If it were up to me, I like the sound of two kids and I want to be done having kids but she attacks me on it and says I'm not giving her the chance to have another. She says that every other couple she knows can all agree on the number of kids they want but I'm an asshole for not agreeing with her. via /r/Parenting http://ift.tt/2Fp3V6e
