Not to the extent of the stories above but my ex did this.
She lied to me saying he was working group shifts and to the OW that his Mum was really ill.
In my case he would wait for me to go to work, go to his own as normal and "leave for the night shift" before I got home. He would finish his normal shift and stay with OW and her son.
In her case he would be at work (they worked together) and then have to go and "look after his Mum" and come home to our house, quick shower before I got in and claimed to have been sleeping most of the day.
He also once went out on a boys night on a Friday and didn't come home until the Sunday. Switched his phone off. I was worried sick.
He pushed back a holiday we were planning as he had to go to a works conference abroad
he was on holiday with OW and her child.
I found out, ended it, told her everything and they then stayed together for a few years. I believe he got another woman pregnant and this caused the breakdown of their relationship.
Ironically I found out because I'd known for a long time something wasn't right. I'd checked his work phone when he did his disappearing act and found naked pictures of another woman. Phoned her and she actually worked with both of them and told me about their relationship. I wanted proof so kept digging and eventually found a payslip belonging to the other woman and several emails.
A million more lies I could tell which I've not thought about for years. It shattered my confidence at the time. I was young, naive and heartbroken.
