I'm a mum to two daughters 30 and 27. Oldest one has done well academically and has a good career, husband with his own company and a baby. Youngest one has always struggled despite my support in every aspect of her life. She has flitted from one boyfriend to another and is now living with a chap who shares custody of his childrenfrom a previousrelationship. They're always broke and the jealousy she shows to her sister is so childish. I do feel for her and I believe she is going nowhere as all her money is in the rented house and helping to support his children, who I have to say are lovely kids. But I feel she's throwing her life away . Consequently, she sees her sister getting on in life and just can't bear it. Please....what do I say to her?
