Do not bring up moving.... the death of a spouse if the largest stress item one can have.... moving is way up the list... do not put stress upon stress....
Also, I would suggest that she find a grieve group... had a sister (and even a dentist) go to them after the death of a spouse and both said it helped a lot... both said it took a year or more to 'get back to normal'.... maybe some here can give more info on this....
Yes, I agree 100%. MIL had brought up moving (not us) and that's when I recommend she wait on that decision so she could stay close to her support group. She has church friends and some new friends she gained while her DH was on a transplant wait list. Staying connected with these friends is going to be much more important to her than her finances right now.
My hope is to help her be at ease with regard to her financial situation (i.e., let her know that she doesn't have to worry about running out of money) and to also help her be at ease with how that money is invested.
