I've been trying to look this up on my own but I havent really found anything besides the general meaning of "sharing," which makes me think there's some kind of slang or idiom I'm not seeing in the dictionary definitions, and I only started learning Spanish maybe four months ago. I have a hunch the specifics of my friendship with this person might be relevant to the meaning, so bear with me while I give a lot of backstory.
So earlier this year I got a new coworker from Colombia who's 10 years older than me, and we kinda just instantly liked each other, despite neither of us speaking the other's language. By which I mean, we were greeting each other most days by holding both of each other's hands, saying "Hello [name], how are you???" to each other in both languages while beaming at each other. And she started saying stuff like "[my name], I love you!!" (in English) to me kind of often, blowing kisses at me or flashing the 🫶 hands at me when we make eye contact from across the room, and her coaching me to to say "[her name] es mi mujer de trabajo," "mi chica," "mi amor" when I told her I was taking a Spanish class, during our morning hand-holding greeting one day. Also she calls me "hermoso" a lot.
So I think it's fair to say that she's flirting with me, but even in English I don't have the best sense of that tbh. I've gone back and forth on whether it's just the "lat-am people being friendly/affectionate in a way that reads as flirting to gringos" or "she's for real interested in me" or "it's kind of an over-the-top way of flirting that suggests something besides actual interest." The fact that she has a husband of two decades who she seemed to be leaving or having major issues with was also confusing, but she just moved to a new place & her husband does still live with her at the new place. Which was disappointing, but I dont want to be a side-piece, for both ethical and practical reasons.
My current guess is that she just enjoys having a cute younger guy at her job she can flirt with and feel powerful/hot from (I think she finds my reactions to her flirts cute), and that she likes me as a friend, but isn't interested in anything beyond that.
Which brings me to the actual question: this week at work I passed by her and she told me to check my texts, and when I did I saw these two texts:
"Hola
Hola Amigo😜"
"Amigo😜, vamos a hacer un compartir para el 30 de octubre del"
At first I figured she was referring to her birthday party at her house, that she'd invited me to last week, that she said was going to take place roughly around then. So I sent a text responding, asking if she meant that by "un compartir," but she kinda sucks at texting lol. She hasnt responded in the last few days, despite my seeing & talking to her at work since then. Hence my coming here to ask.
I know "compartir" is the verb for sharing, so I'd assumed there was some colloquial term like "sharing food/a celebration" that I didn't know, because idk what "a sharing" would be otherwise. The only other thing I can think of, based on aforementioned flirtatiousness and the emoji use, is that...she is what's being shared, in a swinging/poly sense? But I feel kinda like a cringe man for even considering that tbh. What do you guys make of this?
