I speak from the experience on this, and the answer is……… It depends on the couple. I have worked with my wife Terry, at home, in close quarters for about 10 years. We work well together and don’t get on each others nerves (at least not to the point of distraction). We have always understood our strengths and weaknesses and worked together to magnify our strengths and vastly minimize our weakness. We support each others efforts, never putting the other one down. We have the same “Why”, which helps. On the other hand, if a couple needs the occasional separation from their spouse and cant be together 24/7 there could be problems. Also, many times, as is human nature, instead of being supportive, they will put the others “perceived” weaknesses down causing friction and ending many marriages in general. Let me say this, if a couple can work together at home the benefits are Vast as you can GREATLY increase your time and work productivity and also have a partner that you can bounce things off of.. So again, it depends on the couple.
