"I was sincerely coming around to it, Sirius. Since you mentioned it, it had got me thinking and now for you to change your mind!" Dominique continued on at him in French, berating him for being so irresponsible and juvenile, for changing his mind so damned quickly. While Dominique hadn't initially wanted to have children here, the idea that Sirius might never have had children outside of this place, and had wanted to have them here played no small part in her decision.
Dominique frowned and stopped her French. She wasn't even sure if Sirius spoke it and it was rude to fly off into it, something she had been told from a very young age. But when she was angry enough, that's what happened. "Maybe not all of it but it did go into my decision-making process. I mean, we haven't been seeing each other for a very long time. If we were in a normal situation, I wouldn't have jumped into anything so quickly." But as it was she was dating someone younger than she was, who was born a good forty or fifty years before she was and was dead in her time. Not to mention the whole fictional part. Nothing about their relationship was normal.
