That really sucks that your planned long weekend got eaten up with work and fighting I have definitely had similar experiences. I am more of a planner than my bf. I want to wake up, get ready, and go. My partner is not like that. The different styles are a big source of conflict.

Your wife sounds like she is under a lot of stress with this job, so I can see why she wanted to spend the weekend working... and I also have been in your shoes, really frustrated while I am waiting for someone to finish doing X, but they start to do Y and Z instead.

Are you guys at the point where you can talk about how you'd handle it differently next time? Spending time together by helping her work does not sound like something I would want to repeat. Some things that have worked for me are a) not waiting for him to finish, just doing what I want to do and b) making him give me a time when we will leave to do X.
