My wife and I have been married for 34 yrs the marriage broke down about 7years ago when her mother took ill. Since then my wife has rejected me completely and won't give me sex. What can I do? iv'e talked with her about this. She is now staying over at her mothers and only comes home to bring washing and cook her mothers meals.

Am I being unreasonable?
We own our own home which is in both names although I pay the mortgage. I am registered disabled and in receipt of DLA and incapacity benefit. I also have a works pension and receive reduced earnings alowance.
Where do I stand finantially if we were to split up?

ANY question on law needs to include your general locale as laws vary by area.

Depends on whether this is a community property state or other local laws. Also the amount of assets may matter.

I suggest consulting a local attorney.
