Man, I can't see you're doing anything wrong but worrying. And that's not really "wrong," it's normal!

It should work out. Took Winnie (WC/Wild Caught) a good long time to come around and eat outta my hand - about nine months. Before that we never really knew if she was eating the meal worms I got her, but she lived from Oct/Nov or so until March or April being given only meal worms...

Now she eats bunny drumsticks, worms, minnows and fuzzies right outta my hand like she's always been mine!

Your snakey will come around, too.
