Help start new conversations and keep them going with my girlfriend?

We've been dating for almost a month now. We know like everything about each other. But we just cant seem to find anything to talk about. But the hard part is she's a bad decision maker, so she automatically expects me to find something to talk about. Yet theres literally nothing that comes to mind! I hate it. And it just started a few days ago. Please help me. I don't want her to dump me because we don't communicate enough.
