Use the counselor as a facilitator for the discussion. Because you're going because she doesn't know how to verbalize her problem, ie "too good to be true". It is possible that there are other things that are bringing on these feelings in your g/f, but she doesn't know how to get it out; a counselor might be able to help articulate those other feelings. Have a joint strategy before you go in, ie more detail than just "i have feelings of doubt"

And get it resolved before you go any further, ie marriage. And if it can't be resolved, then you have another question ahead of you. Resolved = she may still feel that way but will know from whence the feelings come from, ie from within (or if you've given her reason to feel that way, then she knows it's not ONLY from her, and you also have something to work on (although you don't)). And she (and you) will know what those feelings really are.

That said, I had a terrible experience w a marriage councelor (a man) who completely disregarded my information when I agreed to see him with my then wife. As in any profession, there are a lot of hacks out there, so make a neutral assessment before putting too much information out there. Trust your instincts, don't push off what they tell you.
