In my exs case,he is a psychopath
(Or at least has a lot of the traits)
With a psychopath,one of their traits is boredom-they can start a fight in an empty room,just for something to do
And he was obsessed with sex-he would have had it 24/7 if he could
He was also a cocklodger and really thought his sexy body and good looks would get him through life (to a degree,it did)
He beat me up and ran off with my then best friend-she was desperate for her own baby and tried to snatch our baby on her way out
(she had a lot of mental health issues-an excuse for 'I can do what i like and it's not my fault' in her case-she admitted she puts a lot of it on and she had a doting mother who excused a lot)
They'd been shagging since I was first pregnant-i wasn't up for as much sex and needed sleep and life had become 'boring'
It lasted 6 weeks-her mother saw what a cocklodging loser he really was,had a word and they broke up-the sex wasn't as good when it was out in the open
He also saw a lot of sex workers behind both our backs,using our money
He left for another woman who was very vulnerable and did the same to her before moving away
He's finding out that looks fade and hes not as sexy as he was 20+ years ago and women are wising up to cocklodgers so is finding life every hard and has had to get a job
