Living Apart Together, Con't

I know that Church doctrine tells me that, if possible, I should share a household with my wife, Sarah.  And even if Church doctrine didn't tell me that, I would continue to share a household with Sarah, not least because it is so delightful to do so.

What I want to know is this:  Does Church doctrine tell me that I should share a household with my teenage children (16, 14), no matter how challenging they are?  No matter what their musical tastes, etc.?  I mean, does Church doctrine tell me that I must be a saint?!
