Plus-ones can be a tricky subject...

Your wedding is always hyped up to be the most important day of your life, so is it any wonder a couple would obsess over making their day as good as it can be.
Inevitably, a bride or groom-to-be will make some fairly controversial calls when it comes to what they want on the day, or who's invited.
One bride's divided opinion over her hard-line rules for plus-ones.
"I'm getting married and like every other bride, I too have certain rules I want for my wedding to go smoothly. One of them is the no plus ones rule. Only people named in the invitation are invited" she said in a post on Reddit's 'Am I The A**hole' board.
The ONLY exceptions she outlines for her big day are the following:
"1. If BOTH me and my fiancé know of your partner and have met them. If I know your partner and my fiancé doesn't, that disqualifies them and vice versa.
2. If I'd personally go to dinner with you and your partner.
3. If I'd invite your partner as a separate person anyway and not just because they're your partner.
4. If your partner is also a friend of mine."
"We know it might seem harsh but those are the rules we've decided to set so we can be more comfortable. It has nothing to do with budget or venue capacity. Purely our choice."
To some, the rules coming from personal choice rather than budget restrictions may seem like red flags, but others have said it's her day and she's entitled to the rules?
What do you think?
