We're we not dating?

I've been seeing this guy since August. He's made a point to let me know I'm the only one he's talking to. I asked him to be my boyfriend in December. He said yes.

My roommates went outta town so I asked him to stay with me while they were gone.

The first night were in my room after dinner. We're in bed watching a movie and he takes my hand and says "Are you my girlfriend?" I laughed because I thought he was joking. But he continued by asking "what are we doing here?"

When I asked what prompted that question it had something to do with his coworker asking if I was just girlfriend and he didn't know how to answer. I told him the answer should've been "yes" he said "I know, but I wasn't sure."

The whole thing has me feeling stupid because we've talked a lot about "we" and "us". We've met the friends. We've met the parents. I reminded him I asked and he said yes, he acknowledged both events. What the actual fuck?
