He sounds unreasonable so one of your options is to divorce him now, after 11 yrs you should get a reasonable settlement, it will be less than half so dont expect the moon.
However, he cannot disinherit a spouse, even if he does not mention you in his will, you can challenge the will and claim maintenance. This of course will cost lawyers fees, but probably less than a divorce will cost, so to reassure yourself speak to a solicitor about a wife’s rights when her husband dies. Go to Citizens Rights Bureau first.
Best of luck
