Thank you for all of your responces. There have been developments since my last post.
He has just told his DD that he has come downstairs at 4 in the morning and considered killing himself in order that his wife get an insurance pay out. Unfortunately his DD (in her 20s) didn't handle it very well. Said he shouldn't be talking like that and she wishes he hadn't told her.
Nina, I really do know that suicide is a very real threat. My cousin commited suicide when she was 16 and just 18 months ago my DH was having suicidal thoughts. He is well now and got there mainly through getting the right medication, so my FIL has seem this working.
I am however still very unsure as to where the family should go from here. He is adament that he won't see a doctor and has said that if one comes to him he will leave and "never come back". He is an extremely proud man who feels that he has lost everything. The main reasons I feel as if getting a doctor involves against his will are that:
a) If a doctor came he would feel betrayed and may turn away from his family, (the only support he has) as a result.
b) It would take away his last bit of pride and dignity. We had gone against his explicit wishes and he may feel he has nothing left.
Worst case senario is that he kills himself after a visit from the doc. Then his wife and children would be sure to feel eternally guilty.
The only way I can see it working is that he is sectioned, but this seems like such a horific option in so many ways. I have never seen someone being sectioned before and am not sure he would qualify. He cries a lot, but they don't section people for that. Although he has admitted to suicidal thoughts, this does not mean suicidal intention.
If the doc came round and he put on a good front, then they may decide not to section him, but the fact that they had been would make suicide more likely. Or, doctor could come and he could just storm out and "never come back". Would they/could they physically stop him? He's a big bloke.
I am so aware that he desperately needs medical help, but I am just so unsure as to whether it is right to get it against his will taking all the circumstances into account.
My DH is going up there againn on Saturday. He will confront him head on about his suicidal thoughts and encourage him to talk about how he feels. He will try and assertain how far these thoughts have gone, (eg plans made etc). I have also suggested that my DH tell him directly that his wife can handle losing her home and all her posessions, but would never recover from having to identify his body. This is after all the truth, and I thought it might make him face up to the reality of suicide, ie not being the easy option for those left behind.
Wow. Longest post I've ever written I think! Thanks for taking the time to read.
