If you are considering divorce and there would be money involved, as might very well be case after 10 years, then you need to seek legal advice, in private and without the husband's knowledge, paying in cash, if need be. That is the general recommendation that you will read everywhere - I have never been in your shoes, but everywhere it is written that you first seek legal advice and become aware of your options and strategies, and then start actions/conversations about the divorce. There are numerous reasons to this.

Just make sure that your communications with the potential lawyers would remain private between you and them.
