My best friend and I have been friends for four years. Doesn't seem like much but with everything we've been through together, we became like sisters. Recently she found out that her boyfriend cheated and lied to her. She was broken hearted and being the best friend I can be I was there for her. 1 week goes by and apparently she can't be without him because she starts leaving campus to go see him. Now mind you she can get a ticket and her parents are forbidding her from seeing him. Then she starts lying to me about things. I finally get sick of it and call her out on it and now it seems like everthings different with us. I don't want to stop being friends with her but I don't know if I'll be able to continue trusting her after she lied. What do I do? Did I make the wrong decision?
