To be a bit heartbroken about having a small wedding?

I think it's completely understandable to feel sad about your family situation and weddings bring it into focus

This. I'm sorry your family feels so small. I know the feeling.
I hope your wedding day makes you happy, whatever it ends up looking like x

One of the loveliest weddings I’ve been to was an abroad wedding where there was the B&G immediate family and a few close friends it was absolutely beautiful.

I think it's completely understandable to feel sad about your family situation and weddings bring it into focus. I felt similar attending my friends' big weddings because I lost my mum and several other family members I was close to in my twenties so I always knew if I got married there wouldn't be much of a wedding. In the end, my DH and I just had a practical registry office ceremony when our DC was a toddler and then had two celebrations later with our friends in different parts of the world, and it was lovely in its own way. I've always been sad though that my family weren't around anymore to celebrate with me.

I like you have a very small family, my OH has a large family but whilst we talk when we see each other, we have little to do with each other. We live rurally weddings here are about show and no substance. Whilst I’d love a big wedding I also don’t want to pay for people who can’t be bothered most of the time. The day is about the two of you, spend the extra money on that slightly nicer dress or nicer venue, anything to make your wedding extra special x

It’s the marriage that’s important, not the wedding.

It is sad.
I lost my Mum last year quite young, it has broken me. You wouldn’t know it from the outside as I’m good at “carrying on”.
We’ve decided we’ll elope with our children when we get married as I couldn’t bear to get married without my Mum there.
I hope you have a wonderful wedding, however it looks 💛

True.

@Bubem855 - a wedding is an opportunity to celebrate the joining of you and your husband to be with the people you love and who mean something to you.

DS had two weddings. One had just myself and DIL's DM present (a very quick legal ceremony). It was held in a registry office in a city often voted the most beautiful. Afterwards we took photos and walked to a restaurant with a private dining room and had a celebratory meal with dads, the best-man and matron of honour.
The applause, cheers, horns being blasted and the wellwishes of strangers was totally unexpected, but lovely. It was a wonderful day.
A fortnight later they had a huge affair costing six figures. Whilst it was spectacular, the private day with just the eight of us was my favourite. It was far more personal and we spent the day with DS and DIL. They barely had time to breathe at the 'big' wedding.

The most beautiful wedding I’ve ever been to, had 14 people there, including the bride and groom (my half brother).

Big weddings cost an absolute fortune. I do get what you’re saying but a small intimate wedding can be lovely. We had 12 guests to our wedding, as we have a small family. It was very special.

@Bubem855 We had a tiny wedding with just 18 guests and it was the most romantic and magical day ever. Just close family and friends. For us it was partially to do with budget, but also because we didn't want ro invite people we weren't close to.
Each to their own, but I will never understand why so many people choose to fork out a lot of money for literal strangers to come to their wedding (in the form of a plus one!) I just find that really bizarre.
We did away with all of the who sits where nonsense and had one big table at the wedding breakfast - it was absolutely lovely.
The whole day was so relaxed and joyful.
We invited a few more less-close friends to the evening reception but still kept the intimacy of the whole day.
Zero regrets.

Friends are the family you choose
