"sides" just means someone else who helps us fulfil something we cant for each other. Recently my girlfriend told me she got a "side" and they meet up everytime they go to gym. I figured I was quite okay with this but it costed me a night's sleep and a day's worth of focus. I couldn't understand what I exactly feel about this as I *am* okay with her having a side. Is it jealousy? Or maybe I'm actually *not* okay with it?

Because personal relationships can and do with many people have underlying sexual tension. And most people know this.
There is also always a chance that one of these sides for eaither of you ends up being a better fit then you or her.
So that makes your rightfully feel threatened.
Having platonic friendships are not "sides" with clear boundaries.
It sounds like she wants an open relationship. And you do not.
