Hi JF
Contribution Based ESA is based on your NI Contribution history, as you are in the support group then you will continue to be eligible until you are reassessed and either found fit for work or placed in the WCA group.
From your post you say that your CB ESA is currently a joint claim, you need to check your paperwork carefully as CB ESA is paid to the individual, I therefore assume that you have received CB ESA with IR ESA top up.
Your husbands income will not affect your CB ESA, not even his Occupational Pension but it would affect IR ESA.
Once your are in receipt of state pension then as you stated your husband is no longer entitled to claim CA due to over lapping benefit rules but you can have an under lying entitlement for a HB claim if you qualified.
Income Related ESA is ESA(IR) is dependant on your household income, your savings and assets, and any hours that your partner works.
When your husband reaches SP age then you become a mixed age couple and benefit rules around mixed age couples changes in May last year.
