Ron was ready to discuss what 'benefits' might mean, when he realized he had stepped in it, again. He immediately regretted peeving her; he had been trying to talk about things in a veiled, hidden kind of way, and as she snapped at his comment, he realized he'd botched it. He looked at Harry when she apparated, and said, "I'm sorry, I'm sorry. I should not be talking about this stuff with her. It's upsetting to her, and to me."
He reached out an arm to Harry, to make him pause, "She's not happy with her marriage. She and Stephen barely spend any time together. They haven't even," and Ron swallowed, and moved closer, "Been together as man and wife. When we get there, no more marriage talk, okay? I thought I could get her to laugh," and he shook his head, "Well, that did not work, did it? We can talk benefits later, just you and me maybe? I feel terrible, Harry. I don't want to spoil our time together, you know?"
He nodded to Harry, and stepped in an apparated as well. He caught sight of her, heading towards the shop, and he ran across the street, to catch her by the arm.
"I'm a git, you know. I shouldn't open my mouth, half the time. I'm insensitive, and a louse, and cannot tell a joke for a damn."
He stepped forward to hold her, and comfort her; he whispered softly so only she could hear, "I am so sorry, love. Really, Hermione, love, I didn't mean to get you upset."
