AIO: conversation of my boyfriend and his ‘girl bestfriend’

I didn’t know that he was talking shit behind my back with his girl bestfriend, like yes he was venting but I didn’t expect him to say some words that could hurt me. We spent our 1st Anniversary in Disneyland and I was so happy, cuz finally it’s our 1 year, but little did I know that he was saying bad things behind my back while I’m all there feeling happy.
