I would be apoplectic if my husband suggested this, I'd love 6 months "off" but not when I have a husband, 3 year old & another baby on the way although I do work full time & have done so since I graduated!! bar 6 months maternity leave after our DS was born.
Compromise is the best way forward, what about an extended holiday for ALL of you, somewhere & something that you wouldn't usually be able to do in a 2 week window?

Good luck in whatever you decide x
