Where a middle to late middle-aged man falls so madly in love with a solvent woman with her own home and job that he wants to move in immediately.
Generally, he's living in a bedsit following an acrimonious divorce where the wife naturally 'took him for every penny' and he apparently funds the adult children so much that he never has a spare fiver to chuck into the shopping when the woman has somehow found herself insuring him on her car, feeding him, buying clothes and being sympathetic to his being on the receiving end of age discrimination/he was a sahd/his wife took up with a fancy man at his workplace/he lost his job because she took his car and he's just marking time until
'the house is sold when the youngest hits 18' or
'I will inherit from my mother' or
'I'll cash in my pension to give us a lump sum to travel at an undetermined point in the future which will never come because I'm lying' or
'every penny I earned went to my children except what she took for holidays without me, so I couldn't afford to take a pension out' or
'She even took my pension from mein the divorce'
Basically, he wants somebody to house, feed and clothe him whilst working fulltime and he sits around the house in his pants all day saying she's too old to go out by herself and his back is really, really sore so that's why he doesn't do the vacuuming either.
