You always find something wrong with everyone they're into.
Unless you're in an established, long-term relationship, one of the most stressful things about being invited to a wedding is figuring out how to know if you should bring a plus-one.
There was a time when you were into them, but they were with someone.
But it's nice to know that if you did start dating your best friend, they'll just slide right into family gatherings and skip right past the awkward "meet my family" stage. You've thought about dating them before, then they thought of dating you, but things never lined up right.
If you're super offended, don't attend the wedding, but try not to make it a big deal.
The happy couple is about to drop a lot more money just so you can bring someone to hang out with at their wedding — do them the courtesy of putting your guest's name on the invite.
Because weddings might be stressful, but admit it — they're also pretty awesome.
It sounds obvious, but this extremely important rule (possibly the most important rule) is worth repeating: no "plus-one" on your invite means you were invited alone.
If you were invited with a guest and can't find a date, and you feel comfortable enough to ask the bride or groom if you can bring a friend instead, go for it. Yes, it's hard to plan super far in advance, and sure, things happen — people get sick, emergencies come up.
If the bride or groom doesn't specify what they want you to do, then your best bet is to pay attention to the below etiquette to figure out the right thing to do.
These 12 rules for bringing a plus one will (hopefully) keep you from pissing anyone off, and also ensure that you have a great time.
If you feel like they're checking off a lot of the things on this list already and you don't feel the need to find someone else, then you should either commit to them or cool things down a bit so you can find a fulfilling relationship. You've never tried to set them up with your friends.
This is what separates the "just friends" from the "eh, we're just friends for now." At least once, you've had a few drinks, gazed longingly into each other's eyes, and went at it. You might not realize it consciously, but you'd rather be texting them exciting news than your own SO ... This one sounds cute, but in reality, it's probably not too healthy.
