You might not be in LRT mode yet but other than that your sitch is no different than many. My XW was not mean to me either or overly disrespectful but she was done.
No one here knows what your wife is thinking. Some are done, some are scared, some have left a crack in the door open if the LBS plays his cards right. Some are also done but when they realize the OM is a POS they come back to their H.
Either way that actions you take are no different than what everyone has been telling you for the last several days. Give her space, don't pursue, don't act weak and needy. Work on improving yourself, work on your 180's. BE happy, confident, pleasant and upbeat. Validate and listen.
