It’s true that you will find some yeshivish style people who are lax when it comes to davening and others who are far less yeshivish style who will never miss a davening. However, it was always interesting to me when I came across couples who will have no issue with viewing films/ shows etc., going to exotic locations for vacation that are full of inappropriately attired people (I’ve seen some of the “separate swimming” venues- some of these location aren’t even ostensibly separate) etc.; things that are arguably more problematic on (at least) a Rabbinic level than prayer, yet can’t come to terms with their spouses lax attitude towards prayer. (For example, if hypothetically the only option to pray is to stroll through such an area for an extended period of time so that looking is unavoidable, one would presumably not be allowed to pray).
I not saying this is true in the OPs case but I have difficulty understanding a spouse that views the former as being in consonance with the husbands frum lifestyle but the laxity in prayer as hypocritical, and a contradiction to being frum. If we are talking social/ communal pressure I get that. But if the issue is fidelity to religious observance, why draw the line arbitrarily at a lower level Rabbinic mitzvah? Is it realistic to expect someone to live that kind of lifestyle and then flip a switch 3 times a day to suddenly be motivated to fulfil this particular mitzvah? I know some will say it’s analagous to putting on a yarmulke etc. which makes a statement about ones religiosity. I get that. But that assumes that in the husbands circle quiet absenteeism from davening makes that kind of a statement, and I’m not so certain that it does. And the husband and wife may have differing views as to what if any statement it does make.So let’s honestly define the issue. The issue is not the contradiction to ones frumkeit per se, rather the statement that it may send to ones children or others in the community at large. “The first step is to define the problem”.
