You are obviously distressed, and i am sorry that you are. However we don't have any more to go on than what you have said, and we cannot judge where the right lies here. Perhaps you spoke gently and lovingly, and perhaps your DIL can be difficult. Or perhaps you poked your nose in where it doesn't belong one time too many and she just couldn't keep quiet any longer. You see, we just don't know. I can only work off of my initial reaction, which is this: if my MIL (or even if my own mum had done so when she was alive) started questioning how we were going to afford a holiday and whether we were going into debt to do it, I wouldn't be any too happy, and if it wasn't the first time she had 'expressed her concern' I would be telling her, quite firmly, to wind her neck in. Just how did you 'express your opinion', and why did you think that you had the right to comment to two adult people who, I presume, run their own lives perfectly successfully? And is your son merely standing with his wife, as is only right, or is he too offended by your comments? I sound very harsh, and if i am being unfair I am really sorry, but i wouldn't take interference without biting back, and i'm sure many others wouldn't either.
