I want a baby but I'm not sure if he does.

I want to have a baby but I'm not sure my BF wants to seriously have one. He always says he wants to have children with me and wants to make babies, but he always wears a condom unless we are drunk. He acts like he gets excited when he wonders if I'm pregnant, but I haven't been preggo since I miscarried in September 2014. He has 2 kids already from another relationship and because of that, I'm not sure if he truly wants kids now or if he only says it in the heat of the moment. I feel like I shouldn't get my hopes up since he's always putting on a condom. What y'all think ???
