My wife, on the other hand, is afraid of flying (but has done it twice now, so progress there), elevators, escalators, being near the egde of anything over one story tall, caves, roller coasters and so on.
She knows that these fears often prevent her from enjoying a lot of things in life.
I am at a loss on how to approach any of these things other than to accept them because there is no reasoning with her on any of them most of the time (OK, I did get her to fly the very first time, but that may have been a fluke).
Uhh... wait a second Time. Let me get this straight. You're asking how can approach her so that she can get over HER fears?
Are they causing you a problem? Has she specifically asked for your help in addressing her fears? Have you offered help and she's accepted it, but you're unsure of how to?
My H often used to decide that he was going to 'help' me 'fix' one of my 'problems' or concerns without me asking him to, or without him asking me if I even wanted his input first. It never ended well Time. Tread carefully!
I cannot complain for not receiving from others, that which I've never asked them for.
