Its a risky strategy if you remain in this position too long.
It's later than you think, and trying to get back into the workplace and into a reasonably paid job is tough. Then all of a sudden you're in your 50s, little money, little pension and facing a vulnerable old age.
This happened to a cousin of mine, she is in her late 50s and really struggles. She now works as a carer in a nursing home, it's not well paid, she's finding it increasing difficult as it's heavy work and she's got arthritis developing rapidly but can't find anything else. She's no savings, has debts, rents and is worried sick about the future.
Its also happened to my SIL despite many warnings of the risk of this happening to her. She thought her DH, not a high earner, would always provide for her. She very very reluctantly went back to work in her late 40s (DC were grown up) into a part time low paid role (it was the most she could be persuaded to do) he got fed up and left her as he was stressed and unhappy that they weren't pulling together and he had all the financial responsibility. That was a bolt from the blue as far as she was concerned. She's now stuck in this role as has few skills. She has tried for other jobs but doesn't even get short listed. She got little from the divorce as they rented, children had left home, he had no pension etc.
She's supporting her daughter, who's about to give birth to her second child, in the same lifestyle choice, and both are putting pressure on her daughters partner re this. Neither will listen to anyone else. He is younger than the daughter (mid 20s) and is an unskilled worker in a very manual industry. History looks like it will repeat itself.
