That's just it really.
Yes, you have TIME on your own with the kids but you have someone else to share the tough times with even if it is over the phone sometimes.
You have someone who can take over the challenges of childcare at some stage in the not too distant future that you don't have to pay or feel guilty about imposing on.
You have someone else who is looking out for you even if they are not there all the time.
You have someone else to plan a future with and share decisions with.
You have someone who you can share the money worries with.
You have someone who gives a shit if you have had a bad day.
You have SOMEONE.
I would rather be a lone parent at the moment, don't get me wrong. But IT IS NOT THE SAME PEOPLE so please stop trying to equate the two.
This has probably been done before.
Rant over!
