runforestrun - it can be tough sometimes, but it also has up sides too.
I've been on my own with the DCs for 10 years & these are the things I like:
I'm the boss - so the rules are my rules & I don't have anyone undermining me or arbitarily changing them
I have the entire double bed to myself - I sleep like a log, there is no one snoring, no one duvet hogging, no one fidgeting or twitching next to me. Just complete peace & space.
No negotiating to be done with regard to furniture, appliances, holidays or how the money is spent.
After the DCs have gone to bed, I have complete control of the remote!
I'm not expecting anyone else to help me, not hoping that they might lift a finger, not asking - I just do it myself, or it doesn't get done.
I'm not trying to mood change someone else. I'm not trying to shield the DCs from sarcasm, bad temper & shouting. Our house is calm & relaxing & not stressy.
