Well considering DB's bad rep with relationships, I'm guessing they shagged. 🙂
I really hope they didn't, if they did it would be super inappropriate (in my eyes 🙂) that she keeps referring to him as "her Angel" and "forever her Angel" now that they're both married with kids et al. For a friend, sure. For a former lover... uh uh, totes inappropriate in my eyes! (Maybe I'm conservative there 🙂)
