'My sister is fuming our dad will take me down aisle before her – so declined invite'

Sibling rivalry can be a problem for many.

And it's definitely the case for one bride, who is "gutted" to have fallen out with her competitive sister before her wedding day. The pair are feuding over their dad walking the 29-year-old down the aisle.

The reason? Her elder sister, 33, is fuming that she won't be the one tying the knot first.

While this may seem extreme, the lass is still grieving the loss of her husband-to-be, who passed away in a motorbike accident five years ago. So when she found out her sibling was getting hitched, she was "visibly sad".

The bride tried involving the sister in her wedding planning to ease the tension, but her gesture went horribly wrong. She explained: "At one point, she said, 'I can't believe you'll be the first daughter MY (not our) father is going to walk down the aisle'. I was gutted by her comment."

Apparently, the sister continued to make other jibes too. They included calling the colourful bridesmaids dresses an "absolute circus" and moaning that the ceremony is in September as "it's a bad month for a wedding".

The bride added: "She also didn't like the colours I picked or the dress I wanted. I tried to listen to her sometimes. She continued with her remarks and even called my fiancé to get his opinion. I was fed up."

It was this comment that led to the wife-to-be reaching breaking point. She snapped: "You're out of line because this is my wedding and not yours. Have your own wedding and plan it as you want."

This led to floods of tears – and the woman's mum said she shouldn't have shouted at her "fragile" sister. The post went viral on Reddit, where more than 9,000 people rushed to share their advice.

Many sympathised with the sister while reassuring the bride she wasn't in the wrong. One individual said: "I am sorry for your sisters loss, truly. It sounds as though she has yet to finish her grieving process and this is very very triggering for her. Every bride deserves the wedding they want as long as it’s done with respect and in congruency with their partners wishes."

And another said: "Grief lasts a lifetime, but this high intensity, all feelings sitting right at the surface level of grief usually fades into something more manageable after the first few years. After five years, she would be able to navigate normal family events without being this hurtful to her family. It feels like she may be stuck in an early stage of grief and isn’t able to move forward."
