I would add some depth to this take. How long have you known each others? It might be that she is trying to lighten the mood and, in a misplaced effort to make you happy, strikes the wrong note. This is a crappy excuse an only works if you have been dating very shortly (a couple of months max) and only if, when pointed out, she makes obvious attempts at redirecting. I would not go as far as couples counseling, not worth it if she can’t see the problem and fix it herself.
