You have asked questions on more than two different topics. As to the grand jury testimony, you cannot get it, so that is a dead end. As to "ex-gf" (how can you be sure she is an ex?) and her business, you may have claims but not enough info here to know. As to divorce, you need a consultation to discuss your options. Please feel free to call my office if you would like a divorce consultation. Ten years is way to long to continue to tolerate this nonsense.
Responses are for general information purposes only, and are based on the extremely limited facts given. A consultation with an attorney experienced in the area of law(s) indicated in the question is highly recommended. Information and advice given here should not be relied upon for any final action or decision, as the information is limited by its nature to the question asked and the fact(s) presented in that question. THIS RESPONSE DOES NOT CREATE AN ATTORNEY/CLIENT RELATIONSHIP, particularly considering that the names of the parties are unknown.
Too many issues for a message board. You should meet with a local attorney.
