My b.f & I like many other relationships have our ups & downs and I can truly say we love each other. Many months ago I found out he messaged another girl behind my back. He told me about it because the girl said she knew me and told him she was going to tell me. He called me over seven times that night telling me that his friend was sending messages to a girl on his profile and read me the messages. I told him I was pissed and to shut down all his social media accounts and he did. I believed him when he said it wasn't him because that's what I wanted to tell myself. Later I found out that it was my cousin that was messaging him pretending to be someone else. I didn't confront her about it because I didn't want the issue to get bigger. So I let it all go. Behind me. But the thought lingers in my mind how do you do such a great job of making me feel like I'm the only girl in the world your best friend and soul mate and message another girl behind my back. I don't understand it. It's haunting me. The loss of trust I feel inside.
