Should I cancel

Not at all selfish - I would hope that your husband would be urging you to go too. Your son is going to be there to do anything needful and you'll be back before bedtime, so go and enjoy your outing.

Then come back on here and tell us all about it!

Not selfish.
Enjoy your outing.

I wouldn't worry about it Jeannie, just go and enjoy your afternoon tea.
Your eldest son will be there to look after him anyway.
What does your husband think?

The date of the operation could be cancelled again so you may as well keep to your plans.

Enjoy your outing. I’m sure your son can look after him perfectly well for an hour or two.

No, it is a one off opportunity and you will spend quite enough time nursing your husband after that. Unless he is really upset at the idea that you won't be there, I would go and enjoy it.

Stick to your plans. He will be looked after by your son and I am sure he would hate to think that he had prevented you from doing something you have been looking forward to.

It is quite possible the timings will change again before April anyway.

Of course you must go. It will just be an hour or two before you’re home, your son will do anything that needs doing for your husbands comfort. You never know, the surgery date could be changed again.

Please say you will go, you deserve it and might feel a little resentful if you cancel, faced with a spell of caring for your husband after the op.

Good grief he will have your son there no need to lose your plans there’s plenty more days to spoil and look after him

Personally, I wouldn't cancel. As someone has already commented, the operation could be cancelled yet again. You should go ahead with your outing and let your son take responsibility for your OH when he gets home. From personal experience of hospital transport, there's no telling what time he will arrive home; might even get too late in the day by which time he will be kept in hospital anyway.

Go, and enjoy it! Have fun!

You have nothing to feel guilty about. This is just a set of circumstances outside your control. Surely he wouldn't want you to cancel? If he does, then he is the one who should feel guilty.

Why are you feeling guilty JeannieB44 It isn't your fault the op has been postponed. You are only out for a few hours in the afternoon. Am sure husband and son will manage fine.

You should plan to still go

I’m now curious who the author is!

I agree with the others. You haven't deliberately arranged your outing for the day your husband is due home, so it's not as if you're neglecting him. You've made sure that he won't be on his own and you won't be missing for long.

Also, as has already been said, things could change again between now and then - the date changed, or he could be let out earlier or later than expected.

Go and enjoy yourself. Nothing to feel guilty about.

Go to the event and enjoy it. Your husband will be fine - and he might end up feeling bad if he thought you'd cancelled on his account.

If the positions were reversed, how would you feel about your husband going out and leaving you with your son? Would you feel put out and think he should stay at home with you? I'm sure you wouldn't, and would be encouraging your husband to go out and enjoy his nice experience, and come back and tell you all about it over a nice cuppa with your son.

I hope you have a lovely time

Thank you all for your kind messages, husband is happy for me to go so I will leave plans as they are. Summerlove the author is Jodi Taylor, she has written lots of books the main ones being The Chronicles of St Mary's.

I'm glad you're going. Enjoy it!

Thank you Jeannie I hope you have a wonderful time

Go and enjoy it!

Have a great time. You will have weeks of running around after him!

You must go absolutely,the operation might be cancelled as was the case with my friend 3 cancellations before she was finally operated on.
I do hope this will not be the case though
Have fun

Go and have a great time, its an afternoon not a 2 week holiday.
