Should we change wedding date?

Sounds to me that changing the date would upset the masses (including you -which counts for more than "just guests") to please one person (two if you count FMIL) so I'd stick to the date you have. FSIL already "approved" it (when you didn't even have to ask her) so can't ask you to change after you've started booking things.

Just my opinion though... Possibly see how your SO feels about all this and talk it out

Stick to your guns. If she said she can do the date before you booked, she's just going to have to make it work - especially if you've already confirmed the date with other guests.

Imagine how you would feel if you moved the date, only for her to again say "Actually, that doesn't work for me either."

It's your big day and you have to do what's best for you and all your guests - not just one. Appreciate it might be a bit awkward but I would just say you checked with her beforehand and now that other guests have started to arrange accommodation, it's too late to change.

Absolutely not! It is your big day not hers, she should be bending over backwards to attend your wedding not you bending over backwards so she can be there. It is very selfish and self-centred on her half. You did the right thing and asked her before hand its her fault she didn't organise it before hand. Seriously though stick to your guns other wise you will majorly regret it! especially if you start messing other people around they might start cancelling or being unable to attend, and if your brother is more likely to do those dates than her why is she more important than him?

Its completely ridiculous that they expect you to change your dates because she 'might find it a bit difficult to attend'

So what?

Personally I think I would stick to your original date but I would say that it is really important to talk to your partner and make sure you are both aligned on what you are going to do.

You have already ask her on a number of occasions and she said she would work around you / didn't give you any dates to avoid then I think you have been more than fair. If changing the date was easy i.e no-one had booked accommodate yet, rooms were available etc then I would be more inclined to more it but it sounds like it will create a lot more hassle / upset by changing the date.

I also agree with an earlier comment that what would you do if you moved it and then she said she couldn't make that date either? We had something similar when we got engaged and chose a date as my partners brother then said they were planning the same month for their wedding, so we moved to a different month and then they changed their mind as well and said the same month as us for a second time. We told them we weren't moving our date again, its caused a few problems which weren't nice but it reaches a point were this is your wedding and you have to do what is right for both of you. Unfortunately you can't always please everyone

I hope you get this sorted out without too much hassle!

I'd obviously speak to your OH but she's not saying she can't come, just that she'd find it difficult - so if it were me I'd proceed with the date she already said would work for her - you need to consider your other guests & where they would stay etc, whilst it'd be nice to accommodate her changing requests, you'll unfortunately never find a date that works for everyone when it comes to wedding planning.

Also if people have already paid upfront for their accommodation, I'd find that a reasonable reason to say no if it were me requesting the change of date! But it's your wedding day & if that's the date you're set on, go for it!
