I hope I don't get slaughtered for this, but thanks to climbing London rents and stagnant wages, it looks likely that one or the other of my adult children will be living with me for the foreseeable future. I guess many of us have the same issue, and I feel a bit bad moaning about it when I read that others have terrible empty nest syndrome.
DS is in a London uni and was living in a shared house nearby, so I didn't miss him as much, but he will be moving back in next year, as rents are climbing by the day, and landlords rapacious. We are in quite a small London house, and sometimes I just want my own space in menopause! Especially as I WFH ( no choice) DH WFH most days ( he does have a choice but prefers it).
DD may move back in too if she doesn't get a graduate job that pays enough.
