Did you ask Onyx's question? It's funny, I never would have thought to ask someone outright like that, but it's actually probably a really good idea.
Maybe talk to your DF a bit more about why he doesn't like her? Perhaps he's picked up on something? Or maybe he's just uncomfortable about leaving your DD.

It is generally a good idea to talk to more than one person, if only for a bit of perspective. You might think she's good, but then talk with someone else that seems perfect, kwim?
