The vexing problem of being in a three-friend group.

"Oh look, it's that weird girl trying to tell us there's something wrong in our friendships again."

Wow. That's so mean. But yes, here I am, over sharing once again. 

Today's TMI problem comes from this photo right here.

Sex And The City & And Just Like That stars Cynthia Nixon and Kristin Davis have posted on Instagram a photo together with the caption "Girls weekend out".

Now... The average person would look at this photo and think "That's nice". I looked at this photo and completely spiraled.

There is someone missing from this duo — Sarah Jessica Parker. Yep, you were tricked. This isn't a best friend pic, it's actually a three-friend group pic where one of the friends is MIA.

If you're a fan of Sex and the City, you know that these women are not only friends on screen but IRL as well (except for Kim Catrell, but we don't have time to get into that. You can read about the sub-drama here if you're not caught up on your SATC lore).

I'm lucky enough to have a few different groups of friends. Two of my closet friendship groups consist of three people. Me and two others. Due to my vast experience in friendship dynamics, I am a big believer that trio groups are the most challenging friendships to maintain. 

That photo of Kristen Davis and Cynthia Nixon together immediately made wonder if SJP felt sad and left out that she wasn't invited to the girls' weekend away. 

I then felt silly for feeling sad about a hypothetical drama between extremely rich Hollywood stars who have no idea I even exist. But... the potential taint in the trio is something that I can't stop thinking about. 

With trio friendships, two of them will always be a tiny bit closer to each other — always. You might not notice, and you might not feel it, but it's definitely there. In my trio friendships, I've always been the one who was the "outlier". Yes, my friends love me and will do anything for me. It's not personal, but the two have always been closer with one another than they are to me. 

Watch: Horoscopes in a time of crisis. Post continues below.

I'm privileged enough to say that I'm absolutely fine with that. I get the most joy and security out of my friendships, and I don't feel like I'm missing out whenever two of them hang out without me, have more one on one conversations with each other, or are just there for each other at a higher frequency. 

I get everything I need from my friendships, and I'm grateful just to have such strong friendships that fill my cup. 

However, I do often think about what would happen if it was the other way around. 

In one of my trios, if the outlier wasn't me, I honestly believe all hell would break loose. 

Being the outlier in a trio requires you to be confident and secure in both your friendships and yourself, and to not let jealousy get to you.

You also have to be okay with not taking it personally.

Maybe your two friends are closer because they're in the same life-stage and can relate to each other more. Maybe they could work together, so they see each other daily and have more mutual friends. Maybe they live closer, so they can catch up more regularly. 

Your friends being closer doesn't automatically mean that their friendship is better than the friendship they have with you. They also have the responsibility of being the person who gets the extra set of keys in case the other one gets locked out. They have to organise the group birthday present, and they're the one who's on call 24/7 or holding their hair back after a big night out. 

Obviously, these things come with the friendship, but the good thing about being the outlier in the trio is that while you might not be their immediate go-to person, they're both your immediate go-to person when you need all those things.

Personally, I'm completely fine with that. I know that not everyone would be, especially if people know you come as a package of three. I've had people ask me straight up, "Are [name] and [name] closer to each other than they are to you?" 

In the past, if I was feeling a bit insecure, I would lie. "No, we're all super close," I'd say, because I didn't want people to think I wasn't worthy of a close friendship. However, through talking to my friends and being honest about my feelings, I still feel like they're closer to each other, but I've come to terms with that. They give me everything I need and I give them all that I have. I know that if they needed more than that, I would be disappointing them. 

Yes, being the outlier in a friendship trio can suck, but in my opinion, it's also the easiest position to maintain. 

Oh, and yes, I'm still wondering what SJP thinks about the girl's weekend away. Comment your theories below.
