Sooo......
No offense, but why did you marry your wife? It's not like you didn't knew what you were getting yourself into.

I've found that the key to living together is knowing that the other one is not perfect, and neither are you. The important bit is deciding if you can live with the imperfections or not.
I hope I am not imposing myself, but if you really have doubts about continuing or not, maybe it would be a good idea to take a day off together, go to someplace quite and have a heart to heart talk about the things that are going on.

Communication difficulties can really become a big problem if you let them go on for a long time, to the point where your marriage is over.

Btw, pencil can be finnicky to fax (or Xerox) because it reflects light in a funny way, resulting in very faint copies.
