Simply lying to my wife where I’ve been so that I can weasel out of some housework and maintain shalom with my wife, is lying, not maintaining shalom.
Since you had the option to do the housework, you didn’t lie for shalom, you lied to get out of housework.
The fallacy with lying to your wife to maintain shalom, such as in pba’s case, is that sheker ein lo raglayim, and ultimately, when she finds out, not only will she be upset at what you did, she’ll be even more upset that you lied to her. The best way to maintain shalom (besides not getting involved in these bad activities to begin with) would be to own up, and ask her to help you get the help you need.
