Thanks again for all your responses. I still can't find my thread in "aibu" or in "I'm on", but have emailed mumsnet about it. So I don't know if anybody else can see the thread either!
I suppose it all boils down to trust, but I resent the fact that I am in the dependent position of having to blindly trust while h isn't.
It is very very difficult to talk to h about this as he takes it as an affront and quickly becomes annoyed. I suppose that we do not operate as a team, and I think he has little understanding of what being a team actually looks like. We got together when I was 27 and he was 39. We are now 45
and 57
, but that dynamic of adult vs. child has not changed all that much in some ways.
He bought the house we live in while we were already together, but before we got married. He works very hard and has always worked very hard. Without a doubt he "sweats" (he does physical work) more than I do (and often tells me how hard he works). I on the other hand have spent many years being the dcs' carer. They are now 8, 10 and 12 and I now really feel I should be working outside the home. I am trying to get myself into a position where I can earn money again.
BUT I feel as if my contribution all these years is valued by h to the extent that he provides a roof and somewhere for me to live, but not to the extent that he understands that I need to feel secure, and that I have contributed in many different ways. Our relationship is sometimes ok, sometimes very difficult. Generally h is not affectionate towards me though at our best we are fairly chatty. It is very difficult to talk about anything of any importance.
I think h himself lives "on the edge" in his head so he cannot relate to someone wanting to set things up in a way which he thinks is artificial, or a denial of reality (that we all die), or by lining the pockets of the insurance companies (he said he does not want to play this game).
If he were to die intestate, the 250K would not be enough for me to stay in this house / town, irrespective of the mortgage not being paid off issue.
Also, as people have pointed out:
a. h could leave everything to whomsoever he pleases
b. he could borrow against the property (and I think he has done that to fund other building projects)
c. he could put somebody else's name on the deeds.
I don't know what to do about how I feel about this without causing an almighty rift between us. I really think he has very little understanding of why I might be worried about this (and it has become something of an obsession).
H is very independent minded and I don't think he can conceive of a world where he can't make major work related decisions by himself (like borrowing against the house).
H is aware that I will inherit some money from my family and quoted this in the last argument (trying to downplay my feelings). I really think this is not the point however. I want to be an equal player in our life together. H's latest business venture is a property he bought with his brother and which they are doing up. I heard him talking to him saying how he wanted to set things up for the kids. So in the end it will be h leaving his much bigger pot of assets to the kids (rather than him and I leaving our marital joint assets to them together), while I leave my much smaller (eventually inherited) one to them. At no point will we have been a team.
It is possible that the mortgage includes an insurance but I have no idea if this is the case, and that in itself is ridiculous.
When I brought up some of these issues in counselling 2 years ago (we went for about 4 or 5 sessions together before h stopped coming), h accused me of trying to find all these things out, as if that meant that I was planning mutiny.
He has always been bitter about his first divorce. His ex wife got the marital home while he got a smaller property. I think he trusts no one and is always cynical about people's motivations.
I suppose in these situations both parties think the other one is being unfair - rightly or wrongly I feel sort of "cheated" (and maybe that is unreasonable!). I don't think h realises how much energy I could put into really helping him if I wasn't distracted by not feeling liked / a real part of things / worrying about my future. He just thinks he has worked very hard for many years (which he has).
Anyway, I am sorry, I have gone on for too long!
