When you get married, it's normal to feel like you should be the centre of attention, which is why it has become taboo to do things such as propose or announce a pregnancy at someone else's wedding.
But one woman has been left furious after her future sister-in-law told her she couldn't get married within the same year as her, because she felt as though having the weddings too close together would stop her own ceremony from being special.
The woman explained her future sister-in-law has always had a problem with her because she initially wanted the woman's partner to get together with her best friend, whom the man "didn't like".
And when it became known that the woman and her partner were getting engaged, the other woman was furious - and demanded they wait "at least six months" after her engagement.
In a post on Reddit, the bride-to-be said: "My SO [significant other] and I have been together for 6 years. We got engaged at the end of last year. My SO's brother also got engaged to his girlfriend last year, but a few months before us. They are a couple of years older than us but have been together for the same amount of time.
"When I was first on the scene dating my now-fiancé my FSIL [future sister-in-law] didn't like me, she was annoyed I was dating my SO because she wanted to set him up with her best friend, but he didn't like her. Every time she could drop her best friend's name in conversation, she would, and would invite her to every event we went to.
"Fast forward to now, we all live separately and have our own houses and lives. FSIL still invites her best friend to every event, so we limit how many events we can tolerate.
"When SO's brother got engaged, we were happy for them but had a feeling what FSIL was going to be like. They invited us over to their house two weeks after they got engaged to ask my SO to be a groomsman, and that's when FSIL asked when we would look at getting engaged/married.
"My SO said by end of the year and she said 'well just make sure it isn't within 6 months of us' and laughed like it was a joke, but she wasn't joking."
Ignoring their sister-in-law's comment, the couple decided to get engaged five months after the other couple - which left the other woman absolutely furious.
And when it came to planning their wedding, the sister-in-law demanded that they cancel their plans to marry in September this year, because she was planning her marriage for June and thought the weddings would be too close together.
What's more, the woman's future sister-in-law has also been asking invasive questions about the couple's wedding plans - including demanding to know how much money the bride's parents are contributing.
The woman added: "We got engaged 5 months after them, a month before her 'required amount' and she was p***ed. My SO only called his brother and parents to announce our engagement while FSIL was at work so she didn't get to be part of it. She rang my SO 5 times the night we got engaged and he ignored her.
"She then sent message after message asking for details, when we plan on getting married, a photo of my ring and how long he has been planning this engagement. I also ignored her.
"I knew a family member's birthday was coming up so wouldn't be able to avoid her anymore. At the birthday party, I was making drinks for everyone when she cornered me. She didn't congratulate us but went straight in with the questions. She asked me when we were planning on getting married and I told her some time end of this year, maybe September, and their wedding is in June.
"She then said 'why are you wanting to get married so fast, are you pregnant?'. I was shocked by her question and confused about how a 9-month wait to get married is fast and would be extremely problematic if I was pregnant.
"She then asked how we are affording our wedding and I told her my parents are helping. She then had the audacity to ask how much they were giving us! I said 'enough' which had a double meaning because I was done with the conversation.
"I'm trying not to let her ruin my excitement for our future wedding with my SO."
Commenters on the post were baffled by the sister-in-law's attitude, and many of them warned the woman to "set passwords" for all of her vendors for the wedding so that nothing could be cancelled or changed behind her back.
One person said: "I think it's safe to say that she needs to know exactly zero details about anything that you're planning!"
While another added: "And passwords NEED to be set with every vendor from the very beginning. I could totally see her trying to cancel the venue or other big-ticket items. She sounds unhinged enough to call every venue in their area to try to get info."
And a third wrote: "Please for the love of your sanity, spare not a single thought on this woman. Share as few details as possible with her.
"And if she continues to have the audacity to ask questions, smile and tell her it's comforting to know how concerned she is that every detail of your wedding is perfect seeing how she has her own wedding to plan. Smile, give her arm a little squeeze and walk away."
