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

I'm going to try and keep this short and simple, though it's hard to do because there's a lot of background. 

Basically, my fiance and I are about to buy a house together. I've been wavering a bit with my feelings since we postponed our wedding back in May. But lately, things have mostly been good. 

Buying a house should be so exciting. We should be excited. But all I feel is dread. I could stay with him, and we could have this house and start a family and have a pretty nice life together. But I feel like if I do that, I'm throwing away the rest of my future. 

I feel like if I marry this guy, I'm not going to go back to school (right now I'm helping him run his company – we're successful so I don't feel like I have any right to complain), or see the world or do anything but be a baby factory. Many of my friends are traveling and seeing the world, and I feel like I'm looking down the barrel of a gun. 

And I'm torn, because I do want a family and I do want to be a part of this successful company. This guy is my best friend and he's been mostly good to me. We have our disagreements (he believes mental illness is a sign of weakness, he thinks we should go to church because it's the right thing to do, he feels that bread is an important part of a healthy diet) but I don't think I have it in me to hurt him. I'm terrified that if I throw our relationship away, I'm going to regret it. 

What say you, /r/relationships? Do you have any tips for deciding what to do when you reach a fork in the road?
<bot>: About to make some big and permanent decisions, not sure if I am having cold feet or legitimately concerned that this isn't right for me.
