One foot

I had one foot in the door. But now i want to pull it out and pull back. I knew what i wanted before but i didn't listen to myself and what I knew i wanted. But now that im here...how do i reverse what's happened? Im happy...but not really. I like the situation...but i don't. I had a hand in the door way to catch it from closing but now im thinking about letting it close. And letting the next one open.
I have one foot in the door. What happens now?
