Okay, but as you say, the TX State Bar found no wrongdoing in your complain, and as it is responsible for enforcing the TX Rules of Profesional Conduct, whatever it says, is the law.
The Rule that you quote refers to a lawyer's obtaining your direction as to the general objective of a case. Apparently, your general objective was to obtain a divorce, and the lawyer filed for divorce. The "acceptance of a proposal" refers to an offer to compromise or settle a case. Your facts disclose no effort to settle or compromise, so to the extent that this rule is cited as your argument, it is inapplicable to the facts.
The better rule, in my view, and one about which you did not complain, is 1.03: the lawyer is supposed to communicate with the client -- which apparently he/she did not do very well.
I do undersand that you are unhappy with the representation. I also understand that you believe you received a free consult and where thereafter billed for it. That is abominable on the part of the attorney. But, if the Bar found that this didn't occur, then that's pretty much the end of the battle, unless you want to sue the attorney for malpractice and fraud -- which will be expensive.
What I'm wondering is whether or not your dissolution is still filed and whether you are finishing it with another attorney. I wouldn't want to see your rights prejudiced by your not having suitable representation, because your opponent could take advantage of this.
