<human>: Within six months of the relationship, I told him I wouldn't move in with someone without an engagement ring.

At about our one year anniversary, he talked about how excited he was for us and couldn't wait to marry me.  We definitely had the serious talk.

At 1.5 years (now) he has made the decision to buy a house, wants me to move in with him (I asked advice about that already, thanks for the answers!), and things are moving pretty fast! 

I've been hinting about the ring casually, since we already had a firm talk about marriage I feel awkward bringing it up again.  We are moving in together in a few months...but from what I have seen there has been no initiative in getting a ring, asking questions about what I want, and I know he is spending a lot of money because of the house.  

I know we had a firm conversation about yes, we want to marry each other, yes I need a ring before I will move in with him, this stuff has been said but it feels like he has forgotten that one very important fact...

I don't want to nag or rush, but he asked me to move in with him,  I am afraid I assumed he remembered the terms that I had stated, and isn't picking up on my reminder "hints." 

So...how do I bring it up AGAIN? How do I talk to my boyfriend about getting engaged before moving in together AFTER we already decided to move in together?

Condense the text into a few key points
<bot>: Told boyfriend we need to get engaged before moving in together, and now we are moving in together/How do I have another conversation about getting engaged?
