Hi ce.d and welcome to the forum
I am one of the experts who regularly post here, and I am sure that the others will also share their views with you.
Given your asset position - and I would need to know the level of your personal any any joint debts to be able to advise more fully - bankruptcy would be an option for you, but an expensive one.
Your best option at the moment would be to appoint a matrimonial solicitor to act for you with regard to a financial settlement - which you will be entitled to. Once this is sorted, you will be able to look at the solutions available for you in greater detail, and please use the experts on the forum as much as you like in the meantime.
Regards, Melanie Giles, Insolvency Practitioner for over 20 years.
