The one where I sound like an awful bitch.

I mean I guess maybe I get upset too easily. I need some input from someone. My boyfriend made this friend at work and ended up getting her number and becoming text buddies or something. Oh yeah and I have this problem where I’m really invasive and I go through his stuff far more than I should. While he was sleeping on me I read his messages and he was talking to her all cute and fun. He sent her flirty fun messages and I got thee most sick horrible feeling in my stomach. And I was like wait why don’t I get this long of messages, I get a lot of one word ones. It was all smiles and teasing. I ended up having a panic attack and crying a whole bunch. But I didn’t tell him the reason why. I got more curious and looked at her facebook. Turns out shes this super hot model and my stomach sank again. Fuck. I don’t know if it’s something I should actually be upset about cause there just friends right? Right!? I don’t know if I say something or just try to get over it or what. I really need a second opinion. I know I shouldn’t go through his stuff but I can’t help it sometimes. I’m super jealous and totally freaking out right now. God, I just wish I could feel pretty and confident but I just feel like trash. This is really awful. I feel completely inadequate. PLZ help?
