I guess I've been lucky. My wife accepts my obsession (i mean hobby). Shes never been afraid to handle any of my snakes, she won't touch the nile though. She handles the burms, the kings, and the blood with no fear at all. She is even excited about going to shows.
So don't try to force her to handle or keep bringing it up. You never know she may suprise you and come around. Good luck.
