Break Up & Divorce

What do you do when your “ BEST FRIEND” lies to you about seeing you’re recent ex?

Hi guys. Soooooo I’m beyond angry right now but mostly I’m hurt at the fact that my “best friend” has lied to me and betrayed me about talking to and seeing my ex. Him and decided to cool things down 4 months ago and who has been my shoulder to cry on and hear me out and take me out and cheer me up? My best friend. I’m so upset at the fact that she lied to my face and has seen me as a stupid ass this whole time. I had a bad gut feeling & I had a few people telling me things I didn’t want to believe it but I confirmed she was at my exes place. She’s like oh we never seen each other outside work blah blah blah not even 1 month and they were already hanging out & she lied to me about it. I just want revenge , I want to beat her ass & I just want her to pay for what she did to me. I’ve been calm for a while now but I’m just so hurt. What do you do in this situation? Oh and worst part? She knows that I’m expecting and he’s the father to make matters worst knowing that my pregnancy is high risk I just beyond hurt that she would do this to me.
