Girlfriend (28f), is very very close to her best friend (29f) and it's spooking me (30m) out.

This one is wild and I didn't think I'd be posting about it but something happened recently that's making it hard for me to keep making excuses anymore.

Her best friend since high school is getting married soon and she is the maid of honour. We are nevermets and are meeting in the next few months for the first time ever. It's exciting times.

Some points:

-She and her friend dated in high school for a few weeks until her parents found out so they stopped.

-She is pansexual (only attracted to people's personalities regardless of gender aka bisexual with extra steps).

-She made out with some girls in high school because her ex made her but she tells me that's she's into men nowadays.

Okay, with that out of the way, I'm happy that she's getting back talking to her best friend with all the wedding stuff.

However some of it is bothering me. They've created a discord together after her friend heard that me and my gf have one. I don't know how often they talk but it's a fair amount.

None of this bothers me because I know how close people can get to each other, most of us have best friends that we love and everything is good.

It's the fact that every story or conversation we have has been responded with a story that relates to her friend "oh like that one time me and <friend> did xyz". Like every story for months now.

I know her friends favourite colour is purple and anytime we see the colour purple, she'll giggle.

She calls her "her moon" and the friend calls her "her sun".

They'll have sleepovers together.

She told me that she sent her friend a picture of herself wearing a shirt only with no pants on for "fashion advice".

I know the friend is getting married but I'm afraid that my gf has feelings for this friend. They used to date and only stopped because of her religious parents.

It's the sleepover recently that has me spooked. I asked beforehand if they'd sleep in the same bed or if one will take the couch but the answer was unclear. I haven't talked to her since this happened yday.

My worry is that my gf is closeted and after seeing a post on reddit asking about "wives that turned out to be lesbians" it honestly scared me. I figured that most people by the age of mid 20s would be fully aware of their sexuality but clearly that's not the case.

If this was a guy friend then I would not be okay with any of this, especially the sleepovers (which are uncommon but do happen). Since it's a girl then I look past it a little bit more. If I were to have sleepovers with my girl friends or if I were to interject them into near every conversation then I'd imagine she wouldn't be happy.

Am I paranoid or does this sound a little romantic from her part? Maybe girls can be closer than guys and it's throwing me off.

I'll throw it out there, I've only heard her squeal twice, the time I sent her a package in the mail and when her friend came to visit her unexpectedly.

Any advice or am I being dumb? Thank you.
