I would say that a 10 year difference is practically no difference at all, specially since he is not mentioning any desire to have children, which would require a younger woman. Don't mind the age difference, it really does not matter. There are people here with a 20+ gap and we manage fine.
The rest of the issues are cause of concern though.
You are not free.
Your husband is 82. He could perfectly well live 8 or 10 years more, science is wonderful for extending people's lives. If your husband has seen that you end up with nothing if you leave him, you have to either resign yourself to start from zero at age 60, or put up with your marriage for 10 more years.
You could continue having an affair with your British guy, running the risk of being found out by your husband and left with nothing, or the risk that your YM decides he wants a more local relationship if he feels love-deprived.
Is there any way you could salvage your marriage? Your husband must have had some positive attributes that made you fall in love with him in the first place.
I wish you wisdom for this tricky situation.

You know it's love when the pain of being apart is greater than the pain of being together.
