No wonder male suicide is so high when they get pressure Like this off their own wife.
I wonder how much pressure OP felt when she had a husband and family to provide for on her own for 18 months? I have been the main earner for my entire married life, and I have had episodes where I'd rather have stabbed my eyes out than go in to work. But I also know that without that regular wage i would have more stress and problems so during bad times I took it one day (one hour, sometimes) at a time, and during good times I tried to build in strategies to cope with the bad.
So no answers to that - but dealing with the stress of contract working sounds like the first priority for your DH because that is probably key. And also looking around for something more regular that he would be able to cope with mentally, even if it's less money.
he knows what he is doing etc etc but his actual words just then were ' they need to see how much work I put into that report , and sort out the queries , so they can see how it's done. If I am not there , they gave to work it out for themselves ' wtf logic is that ?
That is the stress speaking and the not feeling part of the team. I've always put more stress on myself to do a good job and cover all bases than anyone else has put on me (and I have had the most stressful bosses ever) and that is something I've finally recognised and am finally starting to cut out the unnecessary stuff. It is ok to achieve 85% sometimes, as long as the basic job is done.
The other thing is: actually nobody is indespensible. When I left my last job i felt, and lots of others felt, that nobody could replace me. Sure, they couldn't because i'd had a 15 year head start. I knew the job and the company and the people inside out. I made them a manual of how to do the various parts of it, and before I left i mentally let go of it all. They will make mistakes, most likely, but they'll learn from them. They won't do the job the same way your DH does, but they'll find their own best way. And yes, they will finally realise what goes into doing the job -but chances are, they won't do some/a lot of the stuff he does. That's how work functions.
Good luck.
