Maybe it is a bit of a riddle. This isn't a confession, after all. The love he feels for her is genuine, but quite platonic. An engagement ring is an awkward prop for his purposes. He can make it work, though.

"Am I? Then, let me put it more plainly."

He takes a couple of steps in towards her, now that the ring box is safely clutched inside his fist.

"I bought this ring for you. When I give it to you, it's not just gonna be a present. I'm putting a lot on the line with it. It sounds like you're ready to accept the ring. But I'm not convinced you're ready to accept everything that's coming with it. This is a package deal."

The words are a bit bullying, but he says them with warmth and challenge in his eyes. They're not meant to tear her down, but to prod her into pushing herself up.
