Money money money

So this is what’s keeping me awake just now. My DH and I are on second marriages and have grown up children who think we are richer than we are e.g. DH’s son needed £700 towards car repairs and DHD &250 last mont. My DD lives in a house that I paid for and put in DD and my name (joint tenants) and she pays me back £400 per month. Yesterday my DD announced that she plans to give up her job and go travelling with her BF for a year. Obviously I don’t want to stand in the way of her dreams and equally I can’t afford to be without the payment she makes. DH and I are both still working and wld love to retire and can’t afford to yet … although if I had not bought house DD lives in we cld stop work tomorrow!
