Lazyemma, you are wrong, I do not have an issue with their staying up later than me - just not that late when there are kids to be cared for in the morning. I am insecure about a lot of things in my life but DH is the one area where I am entirely secure and if you knew me and him as friends in RL do you would understand why. As I have already said he has always been incredibly loyal to me. And in fact I went to sleep for a couple of hours and was woken by the noise two hours later.
DH totally accepts it was his fault and I think it was more his fault but every time she comes to stay she (and therefore he)is up till the early hours - he is normally not up much more than an hour after me. Every time she stays it has woken me and every time I have got upset and I thought she realised last time she stayed that it was an issue, and I hoped this time without having to spell it out that she would be more sensitive. I did tell her the day before that I wasn't getting enough sleep, and I personally would have had the sensitivity at least after the last time she was here to have realised it was an issue.
I personally would not have behaved in the way she did if the situation were reversed. I would, as Jimjams says, have been tuned in enough to her life to have been sensitive to her needs. I do accept however that she is not a mind reader and maybe I should have spelt it out clearly like Jimjams did with her family beforehand that whilst I don't expect her to go to bed at the same time as me I would appreciate it if she didn't stay up so late this time.
We have argued about it again today actually as she contacted me and said she was upset and offended by my accusations even though the first thing I said to her was that it wasn't about wrong or right, just that I felt unsupported.
DH accepts it is his reposnsibility, but didn't like the way I came flying down at 2 am all upset which is fair enough, and he also says that he doesn't even care to stay up late talking with her but feels it would be rude to leave her sitting up by herself.
I think we all judge things by our own standards and I think that I as someone who is permanaently sleep deprived and has quite a difficult life with DS1's additional needs would not have behaved that way but I guess she has a very different life and feels differently. She did say she ares about my feelings and would behave differently next time which is the main thing.
