And I am totally horrified at my actions.
DH & I have been having marriage problems for the last year. I love him very much but I find him very controlling.
He's very critical of me & I feel like I can't do anything right.
For example, I couldn't order the curry last night, I had to wait for him to get in from work. Obviously I'm unable to use the phone- I'll only do it wrong.
Fast forward to today, we were going out together, I was supposed to drive, prearranged. I could see how difficult it was for him, noone ever does anything as well as he does.
DH proceeded to tell me slow- fast- watch your speed etc. this was continual he then told me where I should get off so we could enjoy a cup of coffee. When I dutifully pulled of he then directed me where to park 
I expressed how unhappy I was with the constant commands & he apologised but got cross with me, he then told me to shut up as he'd apologised.
Once we got inside I went to find a table after 5 min DH hadn't joined me. I went looking for him and he was sat elsewhere eating & enjoying his coffee. The silent protest of a manchild.
That's when I did it.
I went.
I left him 60km from home at a service station.
Holy shit.
