Everyone is traumatised by the awakening path. I was when I first started 6 months ago.
It doesn't necessarily means you are incompatible. In fact, she could very well be your ideal soul mate (separate from "soulmate"" or even your twin flame! If not, perhaps a kindred spirit. It means she is awakening from the illusion. From the conditioned self.
And people are waking up! Channellers and popular spiritual YouTubers say a mass spiritual awakening is happening on the planet right now! This is to be expected. Thank you for helping the human collective's Ascension!
To console your girlfriend, who is dominated by the mind and not the soul - consciousness - I would show her this:
Love and light
