The never ending goodnight,

So my girlfriend and I text each other pretty much nonstop. It's kind of sad.

So as I was going to bed the other night I texted her good night.

She said it back.

I said sweet dreams

I got back a "you too"

And before I know it half an hour had passed before we finally say goodnight to each other and stop texting. I think there may be something wrong with us.
