I just want to thank the OP for being such a good friend to "Ann".
You guys are really looking out for her, including removing her online "classified" post that was downright dangerous (i.e. advertising for a man with no thoughts to safety). Sounds like she was not thinking correctly and needed some tough love about how she was going about things....
It also sounds like she is just not in touch with her new, widowed reality and needs time to grieve.
Consensus:
- get a small Class B or C that she can travel in.
- join with you & your husband for some short trips
- join a camping group and become active
- take these small steps and her "Dream Trip" will most likely fall into place, and she won't be flat broke (Class A mistake).
But in the end you have to remember, "It's HER RIGHT to make stupid decisions that can A) get her physically hurt, B) ruin her financial stability and c) break her heart emotionally.... you can only advocate, plead and steer her so far. Then you just need to hug her, wish her good luck and step back. But be prepared to rush to her assistance - ONCE. If she keeps taking advantage of your good nature and love for her (by causing you to worry & lose sleep and solicit online help to make her see sense) she's not such a good friend to have.
Even competent adults are allowed to act like dumb, irresponsible teenagers again :)
