If you're going to undertake treatment do it for YOUR own dream not your husbands
But what about her children?
I mean having a phobia of spiders is one thing, but curtailing whole family travel is another!
If my DH had this phobia I couldn't help but feel bitter if he didn't at least try to work out how he could learn to over come it.
If he didn't try and just said " stop trying to make me" I would feel very bitter..
If he tried every which way....money allowing....and still couldnt, fair enough.
You see to me the worst that could happen is, you do eventually work on it and at least come to a point where you are able to get on a plane, and get through it, as lots of people with this fear do....and then you realise it was bad but not that bad...and...you wish you had done it sooner and all that wasted time you will never get back! That to me is the worst case scenario..
I have known varying degrees of this, one friend was terrified, avoided even short hall etc, but had to do one long haul for work...got in a bad patch of turbulence, really really bad! Then his work took off and had to fly long haul, but there was no way round it, it was either fly or stop the business ...he had too and he did it and does it.
to lower grade fear, dealt with by stiff drinks, tranquilers and so on.
