<human>: As it says in the title, boyfriend and I are a few months away from graduating college and we've been together 3 years.  We both come from traditional families. My parents were each other's first and only partner, and have a great marriage.  His parents are similar.  For this reason, I've always greatly valued marriage.  Long periods of cohabitation don't really appeal to me.  I don't want a giant wedding, but I do want formal commitment and legal protections.

Our plan was to get engaged after graduation, move in together (he got a job in the city where I'm going to grad school), live together for a few years, and get married after that.  We're on the same page with children and everything.

Recently my boyfriend hasn't reacted well to me talking about fanciful future stuff like kids and weddings.  I asked him if anything was wrong, and he says he doesn't know if he's ready to get engaged yet.  

I understand his perspective, but it makes me wonder if I was doing something wrong that's putting him off me or something.  Am I no longer wife material?  He says he still wants to live together, but I'm torn.  I always thought I wanted engagement before moving in with a man.  

I want to believe him when he says he still wants to marry me in the future, but I'm afraid this is a sign of him inching further and further away from me.  I'm not going to break up with him over this, I just want a little peace of mind.  Any advice?

Can you give me a shortened version of the text?
<bot>: My boyfriend and I were going to get engaged around graduation.  Boyfriend is now having second thoughts, but still wants to move in with me and take our relationship forward.  I'm conflicted.
