Wow! For starters where are you having the wedding? Is your saving £5k causing your guests to effectively pay instead in terms of accommodation and time off work?
Midweek weddings are a pita for most people.
If you're SAVING £5k by having it midweek that means you're SPENDING quite a lot of money on it. This is unnecessary and quite honestly as you clearly are not particularly hard up I think it's unreasonable of you to have a midweek wedding and pass the costs on to/inconvenience guests ESPECIALLY bad when it's close family you're inconveniencing/offending.
Yes it's your wedding BUT the well mannered, polite thing to do is to at least give SOME consideration to guests needs. I honestly despair at the "your wedding you do what the hell you like" bollocks!
Regarding your conversation with future fil ONE HOUR and you've taken umbrage at his not replying?! Wtf!! For a wedding not happenin for 2 bloody years! He could be eating, having a bath or even he might be working out perhaps in discussion with future mil when he'll be free to get measured?
You seriously need to
A chill! One hour is no time at all to not respond to a query
B start being more considerate of your fiancés family who are soon to be also YOUR family
C give serious consideration to rethinking this midweek wedding if it doesn't suit the guests you AND your fiancé most want to attend. You can't accommodate all guests needs but it's plain good manners to consider basic needs and to try and accommodate as far as possible those closest to you AND your fiancé.
D chill! Yes I'm repeating myself cos you REALLY need to. 2 years! If you're like this now you're gonna be murder to be around in the last 6 months before it! It's ONE day, it's important to you and fiancé and your close family but beyond that it's just a one day event.
You're going to (hopefully) be part of this family for decades, you need to be much more patient and thoughtful and stop expecting them to dance to your tune without being willing to compromise.
"His parents do work and they do work Monday-Friday job. As do my partner and I. However, the majority of our family and friends work shift patterns all over the place, it’s impossible to please everybody." You can't please everybody BUT you should try and accommodate the needs of those closest to you.
"I remember their specific point being “We won’t be able to go on our two two week holidays and mini breaks”. They were bothered about using annual leave and how it would affect their multiple holidays abroad." So they WOULD need to take what at least 2 annual leave days for your wedding from the sounds of things and that will likely apply to the majority of your guests too! That's selfish! You ARE passing on the costs and inconvenience you're avoiding to your guests. That's rude!
Quite honestly considering people naturally write with a bias to paint themselves in the most favourable light and those they're in dispute with less favourably and you are STILL coming across as v unreasonable I'm willing to bet even the fallouts where the future in laws were apparently unreasonable there's likely FAR more to it, eg I suspect they may be feeling op is pushing her fiancé into decisions that aren't in his best interests and which they know (as they know him, having raised him) he isn't happy about. You seem very determined to get "your way" on pretty much anything and the thread title I think belies your true attitude to these people. Even though you've basically tried to backpedal from op on.
Your life doesn't occur in a vacuum, neither does a marriage. You're gaining not only a husband but also a family, something people these days seem to want to deny? But that's not how it works.
Yes there are sometimes families who are genuinely abusive, argumentative etc but I (and it seems others from responses) am very much getting the impression that op is type to cause an argument in an empty house!! So I'm highly sceptical of the claims of future in laws being the ones behind all the arguments.
"I can forgive him for the way he has treated us and I thought an invite to our wedding would demonstrate how much he means to us"
ffs! You've really got tickets on yourself eh? It's not a bloody royal wedding! YOU haven't behaved well either, it takes more than one side to argue - have you apologised to anyone? Taken any responsibility for your part in all this?
"For those commenting bridezilla blah blah blah, you couldn’t be more wrong." Oh my god get OVER yourself!
Having guests who are friends or more distant relatives not attend is sad but no biggie - but you'd actually rather dig your heels in about a date nobody but you and fiancé give a shit about (from the anniversary perspective) that causes inconvenience and SIGNIFICANT extra costs to guests than have YOUR FIANCÉ'S PARENTS there? Wtf is wrong with you?!
THEY are more important than any date on a calendar! Your priorities are fucked up!
"then I think that speaks volumes of how little they care" and yet zero self awareness!
"His parents bring in approx £5k per month between them"
1 that's none of your bloody business
2 neither is what THEY spend THEIR money on.
"which we thought his best men" he's having more than one best man?!
"So me contacting him as I have done today, was my way of saying I’m in a place that can forgive him for all of that" oh how big and magnanimous of you! - where's your apology to them?
"my way of saying ‘I know you’ve made some bad decisions earlier in the year but if you’d like to, we’d love you to be part of our wedding party" the sheer level of arrogance is utterly breathtaking!
Seriously you need to chill, apologise, stop banging on about the damn wedding but also give serious thought to changing the date. It's meaningless to anyone but the 2 of you and a ridiculous reason for choosing an inconvenient and expensive setup for your GUESTS.
