Probably Better Off...

So me and my fiancé have been talking about a child for a while, I'm in college, he has a stable job and rents out an apartment. We believed we were stable enough... but the other night I told him I was pregnant ( not a joke ), and he was actually upset. Which I got completely confused by, and didn't understand how all these months a child was a yes and now that I am , he was saying no... basically, he wants to get another job and he wants to be more stable.
