Holly, that was a kind and caring post. I take some of your points but I do not feel that you can be held responsible for advice given that doesn't work.As it stands nothing has worked for years.
Lets face it this is like watching a train crash in slow motion. I am not sure I agree with taking advice from children in this, her son particularly has played both sides against the middle and imo is not to be trusted and I do feel that they are still children and are naturally concerned for their financial future and stability. That is perfectly understandable.
I have never been offended if people do not take my advice,but I do get frustrated when stories change and are contradictory. I for one cannot keep offering encouragement and cheerleading type comments if I actually see nothing has changed. What's left words of sympathy for the life she is living- I can't see that helps. I can not see anything changing in MWG's situation unless she takes active steps to change it. I see bankcruptcy and heartache unless FIL bails them out. Her h appears to be quite settled as things are. However if as you say there are many things we do not know about then it is hard to offer an opinion. I am glad she has such a good friend in you and really hope that at some point soon she will have some control over her life. I really do wish her well.
