If you have an ex that left you but they then fell on hard times and literally the only option was to sleep at yours or they sleep in their car (realistically this would be reasonably long term)
Would you let them sleep at yours until they are back on their feet
(The council were contacted and no realistic opinions were provided)
The ex was really nasty during the divorce, saying lies all over social media, argued with all of your family and has also been quite nasty since the divorce
Though if nothing is expected of them (such as helping to tidy up), will be quite and enjoys spending time with the kids
