<human>: Can you condense the text into three sentences or less?

I thought my BF and I were on track to get married and have kids. We've been together for 4 years and we've always talked about what our kids would be like, our parenting style, and he's even been dropping hints about looking for a ring. 

I've always wanted to be married before bringing a child into the world, partially because I'm old-fashioned that way, and also for security. It has always been non-negotiable. Now that I'm pregnant and two long-term commitments away, my BF apparently doesn't know if he ever wants to get married or have kids. 

I don't see how we can have a future anymore. I'm crazy hormonal right now so i don't even know if how I feel is real, but it feels like this relationship is over. He says he wants us to be together, and that it's possible that in the future he might want to get married, but there's just something preventing him from being okay with it. To me it sounds like he might want to get married, just not with me. 

Is this relationship doomed? I feel like I already know the answer to that but the crazy hormonal part of me is saying maybe I'm wrong... help.
<bot>: BF of 4 years doesn't know about marriage or kids anymore now that I'm pregnant. Does that mean we have no future?
