Feeding my ball python?

[Arcapello]

Today was my first attempt at feeding my ball python. It was a f/t mouse, but he didn't eat it. I'm almost positive that it's due to me not preparing it right. I've read more about thawing the mouse, and am planning to try again in 5-7 days.
My question is: Should I leave him alone until he's eaten? Or can I get him out?

I'm assuming that I should leave him alone, but I thought I'd get everyone's opinions.
Also, I'm planning to leave the mouse in a ziplock baggie in warm water (switching the water every once in awhile). How long should I do this? I'm going to throw this mouse out, and buy a new one.

Leave him alone till he has eaten.
might give him 3 or 4 days and try again.
thaw out in warm water then heat the head with a hair dryer before feeding.

He was eating f/t. It's not his fault, though. I didn't thaw it enough, from what I've read. I'll make sure I do better next time.
