Is it just me?

So like when you have a feeling that someone is hiding something from you, you normally try and find out who or what they are hiding. So like my bsf she's been acting kinda fishy lately. She's been acting like she knows more about Elliot than she's telling me and that she seems to think and or know something about him and me that I don't know about. I feel so stupid right now. Like this just can't be me that's only seeing the fishyness. All I see is the way that she makes us flirt with each other without us noticing. This shit is all a scam omg. I found out the thing. He might actually like me and she knows or she's just being this way to be this way. I have no clue.
