Only time increases the weight, makes heavy real. Take a minute, along with a dozen or so deep breaths, to remind yourself of that. Seven months is only seven months. This is not Hiroshima, no matter how it shakes out; it's two grown people who, five minutes ago, were not a couple. If you're incapable of seeing that something is amiss. If your inner clock and scale is outsourced to another person that quickly something is amiss.
I can spin a number of hypotheticals here. On the "everything seems to have changed" front, for instance, I can say that maybe what you're learning is that your girlfriend is not nearly as mature as you'd hoped. You have a kid, have spent time with kids. Show them a rollercoaster and they are the happiest human on the planet, and about the most fun human to hang out with; but once they have to wait in line to ride the rollercoaster they are the most miserable human on the planet, and seriously annoying company. But, of course, they are children so it's all good. Adults who behave like children, who need only candy and rollercoasters to be good company? Not cute, at least not for long. Not all good. She may be such an adult—and, sadly, you started to learn that after sharing keys.
That said, this didn't all just "happen" to you, but something you've made happen too. You're touting your relationship credentials like an MIT physicist listing his degrees to explain the laboratory he blew up; all those smarts aren't putting out the flames, you know? No, the laboratory blew up because he was too stoked about the experiment to access all those smarts, or because he still had a few things to learn and the fire is a reminder of that.
In your shoes, I'd be focused on that—the gap in your own education, now coming to the surface—since you've got no control over her but total control over yourself. You're a touch sick right now and recognizing it. Treat it—not with the relationship medicine, but the real medicine that allows for healthy relationships: with yourself and, by extension, with others. If you have a history of using relationships medically, give that some reflection. If this relationship is making you sick, give that some reflection. Therapy is where we go to become better at reflecting, not where we go to get gold stars from our partners. And with better reflection comes better partnerships, because we're less inclined to use partners as mirrors that only reflect back a version of ourselves that we want to see, while hiding the rest.
