My exdh can not leave a BBQ alone - even at some one else’s house.
When I was nine months pregnant with Dd3 and looked like a hippo we were invited to dh friends house warming BBQ. I’d never met him. We went and took dd2 who was 2 at the time.
It was also a joint 21st an the house was packed.
Dh basically bloody left me to fuck about with the bbq and I didn’t know any one there so sat at a random table with people I didn’t know and trying to watch dd2 as she was getting lost in the crowd. I got up to get her and some one fucking stole my seat.
I went to find dh and he seen me and gave me a 2 mins sign with his hands. So I stood there like an idiot in the middle of the garden with people milling about sweating as it was hot. Then his friends wife came over and told me to get to the back of the queue 
I wasn’t in the fucking queue.
I skulked away from my non pushing in queue spot with dd2 and found a chair in the living room and sat there for nearly an hour hormonal and holding tears back, fuming at the queue police and my ex.
When he found me I made him take me home. I also made him take me for a burger on the way back.
I’m still really salty about that.
