If we define fake frumness as acting frum but not having any relationship with gd (ie not davening to him etc), then I hear what you are saying. Otherwise this needs work....
Better question, why does it bother YOU that he doesn't daven? Just cultural, or you are disturbed by the lack of commitment? Do you daven?
Yes, you got my definition of pseudofrum.
It bothers me for a few reasons:
1. As mentioned we are buying into the exorbitantly expensive frum lifestyle
2. We (personally) have a lot of daven for (not just in a general world peace kind of way....)
3. Like
@iAm mentioned, my daughter is nearly 3 and I want her father davening to be a part of life.
4. It makes me not respect him, because I see him as teenager slacking off, not taking his responsibility to his family, to his parenting role seriously
5. I daven on occasion- but then it's not my mitzvah.
