[edited topic title to reflect actual intent of this thread. The original title was "How do you ignore your wife", to which the answer would obviously be "you don't, but you can do so and so to manage your family/work time". I believe this is known as a loaded question (thanks hodgman), not intended to be answered on its face.]
So my wife doesn't have a job even though she has a college degree (v. high unemployment rate in our country), we don't have kids yet, so she pretty much has nothing to do all day. I return home from my day job, but I'm finding it pretty difficult to sit at my computer and work for any considerable length of time without it causing her to become upset. I've talked with her repeatedly and I feel she understands and tries hard to not be demanding and let me work in piece, but the truth is that it's not working, and she always ends up feeling lonely, sad, and ignored. I don't feel it's her fault, but I do know it's seriously getting in the way of me working on my indie project. It's not that I don't want to spend any time with her, because I do, but it seems that as long as I'm at home, I'm expected to spend ALL my time with her.
Yesterday I stumbled upon a story about a failed kickstarter project that ended up costing the developer his marriage specifically because he worked too hard on the project at the expense of spending time with his family. It caused me to worry. For people who work on projects after their day jobs, how do you ignore your wives?
