Kirkcubbin, I'm so deeply sorry. Such a painful story! I just hope you're exaggerating when you say ds' life is 'ruined." He can leave dil and find another, nicer lady, surely?
Jimmy, groan! Your situation sounds very difficult. But, at least, you have both dss in your lives. Would it help to just make up your minds not to discuss one's business with the other, period? No "tinterhooks," maybe? Just don't bring one up to the other and vice versa. If they don't care for each other, that's sad. But it also means they don't really want to hear about each other, surely, and they don't need to know. Does that make any sense?
Milly, I feel for you, too. But wait... GD and GGD? Did this begin with your DD or DS? Or is there some kind of issue between you and GD herself? What do her parents think?
Margarette, congratulations on eldest gd's successes and those of your dh's gds, as well! How lovely that you have a good relationship with those 2, also.
Glad that elder d found her way. I understand it's hard for you to be proud of her because of her attitude towards you. But I'm sure something in her upbringing - the way you raised her - led her to setting and achieving a professional goal. Obviously, she stopped to have children along the way, and it's good to see that at least one of them is doing well, too. It's all part of your personal legacy, imo.
I'm sorry elder d's dad died so early, and that probably didn't help her attitudes. Also, I'm sorry about the issues between you. But you have others who love and appreciate you, and I hope you take some comfort in that.
