May I ask you a few questions? I gather from your post that you are married to your husband for at least 30 years but lately he is taking over whatever you are doing, and either giving you instructions or completely redoing it. Have I read the situation correctly?

Based on this post, I would like to ask you if you have discussed the issue with your husband. Has he explained why he has suddenly started to micro manage you? What is his take on it?

Also, what is causing this reaction in you? How are you perceiving his actions? What do they mean to you? Have you explained to him (calmly) how his actions are affecting you?

I am not aware if you have posted earlier about this. If you find my questions irrelevant please feel free to ignore them. I hope your problem soon finds a successful resolution.
