This is about 14 years ago.
Things were very bad with my now ex.
My extended family were meeting by the coast for a couple of days.
I told ex I was going and taking our sons with me. Booked a Travelodge.
He knew where I was, when I would be back, who I was with i.e. I was fleeing with his sons.
Checked in and went out for the day with my family.
Got back to find ex in our room. He'd told reception he was my husband and they gave him a key card. He didn't want to be with us, he just wanted to fuck it up for me. He was so smug about it.
The room was booked by me, in my name and paid for by my card.
I def didn't complain at the time - it would have made a scene and I was ground down.
I can't remember if I complained later, I know I thought about it.
