Rant away, I completely understand what you are saying.
Your post and another about lonliness got me thinking about exabf....
He was supposed to cut the lawn...in three years he did it 4 times...
He was supposed to put the garbage cans out to the street for collection...he did it twice.
He was supposed to keep my vehicle washed n waxed...as he did not have wheels...he
washed it 3 times and never waxed it.
Once in a blue moon he helped me bring in the groceries.
And...the list goes on...
So, what did I need him for? Nothing, Nada, Zero. I also realized that under the drama
and chaos that I so clung to, I was bored to tears. Hearing the same stories, over and over again, the whining and crying about his issues (all of which he created) and the constant "What can you do for me today" mentality...BORING!
Aahh, I feel better, ranting does help!
