don’t know how to handle the situation

I don’t wanna sound controlling or anything like that but I can’t help but feel hurt about this. My friend got me this guy’s number the other day when I wasn’t at school. I’ve had my eyes on him for months and she knows that. Him and I texted a little bit but I’m not super bold so there hasn’t been much conversation since but eventually I will be more comfortable enough to open up. Though I just learned that my friend went out of her way to find this guy’s snapchat and text him too and apparently they’ve been talking all night long. She knows I’m not bold so she thinks that makes it okay and she also thinks I’m talking to a different guy which I’m not at all, I don’t know why she thinks that. And I’m just hurt like why did she help me get his number in the first place. Because I know for a fact that she’d be furious if I did this to her which I wouldn’t do in the first place. Idk what to do or how to not come across as controlling and annoying cause I don’t care who she associates with but this just doesn’t make sense.
