Sys2ad2, I think you are being unduly pessimistic. How assets, fixed and income, are divided between a couple when they divorce, is meant to give parity to both parties, but how that is done varies from couple to couple and depends on a whole range of factors depending on how long you have been married, possibly how much each brought to the marriage and many other factors.
The only way to find out how a divorce will affect you financially is to visit a solicitor specialising in divorce, let him know what your and your husband's financial situation is, including the extent to which you paid off debts etc. You may find the situation is better than you think.
