You could, but imo it’s different when there’s kids involved. No one forces you to have kids, and until they can fend for themselves they are wholly dependent on others for care. If you’re absolutely miserable and/or their welfare would improve with you out of the picture then so be it, otherwise you have an obligation to them to see them through to at least self-sufficiency.

Unless you were just telling a joke, in which case sure.

Yes.. think of it as an oxygen mask, if in lets use stress as ‘the plane is going down’ then u take the oxygen mask once your ‘oxygenated’ then you are fully equipped to pass to your children and help them better… basically think of yourself first, if you go down u all go down!
