Own money/pension pot

Sounds like you will be the one who is supporting you both in retirement. He has a problem but is refusing to acknowledge it. When funds run out he will in all probability start to look elsewhere to fund his addiction. It is an addiction and an illness. Help is available but only if he asks for it. The only thing you can do is speak to him and let him know that his secret is out and your financial future is at risk. I would also take steps to protect your own finances as much as you can.

Be very careful Young Nannie. I know of a case where the wife suddenly found out that her husband had taken a second Mortgage on their house. He had forged her signature on the documents. It transpired that this was to cover his gambling debts. I would keep a very strict eye on all the post coming to the house and be very wary of any suspicious phone calls etc.

Is you marriage otherwise happy?

If it is I suppose you encourage him to seek help for his gambling addiction and if he'll do that you support him.

If not, you need to seek legal advice to freeze your assets as it sounds like he has a very serious problem

Sorry to be so blunt but you go round the houses with this one

He has a problem and if you are relying on a joint financial future you are in trouble sadly.
I feel you need to do something really quickly to protect yourself and your finances. I don’t know where you should start but you must!

If it is a joint pension how can he access it without you?

To me gambling is a waste of money however if it is his money he can do what he likes with it.
