Your answer would be...

Ds 19 asked me how I will cope when youngest dc leaves home... Youngest is 6..
His mate's dm apparently went to pieces.
He asked what the focus in my life will be.
I said my ddogs!! Maybe not all of the ones we currently have. But I will hopefully always have ddogs..
Dh did his best flounce ever!

Oops.
Should I have said dh will become my sole purpose??

Well I have a non cohabiting dp rather than a DH and in about 10 years when dcs are adults I hope we can prioritise us a bit more but he won't be no1. That'll be me, my headspace, my home, my hobbies, interests that have been about 5th fiddle to everyone else as a single parent.

I would have said I would try to devote more time to volunteering. DH wouldn't care if that was my answer as despite being in a relationship we are still our own people.

You should be your priority. No one else especially when the kids have left home. Life will be about doing the things you enjoy with people you like (dogs, dh,friends and seeing your adult children) doing things you like (hobbies, travel and interests) relaxing, enjoying work (you might be able to work doing something you like not just because it pays the bills)
