Serious question.

OK, so, my husband is on the fence about having a third baby. He goes back and forth. He tells other people no he's done sometimes, other times he says if it happens he would be thrilled. I've asked him so many times to just decide. I want our kids to be about 2 hears apart, so we need to start trying of we are going to. With this said, I'm on birth control.. I'm seriously considering just stopping it and not telling him and just letting things happen. If it's meant to be it will be, if not then we don't need to have this constant back and forth conversation. Is this terrible of me?
