Hmmm... 3 questions came to my mind when I read this:
1) How long have you been dating?
2) What do you do when you're dating?
3) Is there anything specific she says that bothers you?
If you're in the early stages, maybe she's just having the jitters and needs some assurance. It might help if both of you got involved in outdoor activities that required more physical exertion (so there
isn't much time or energy left to talk). Then maybe hint that it's nice to have a companionable silence
But I tend to agree with some of the others - if you're seriously bored and irritated by what she says, do a favour to yourself and her by ending it now. Just because you know she adores you is no reason to stay attached, because that in itself is not sustainable. One day - be it in 30 years or more from now - you will still break off if you're not right for each other.
