My boyfriend and I have been together for 2 years. In the past he has lied to me about talking to other girls. He also broke many promises. He promised he'd stop talking to his ex multiple times. Each promise he broke. He's back to lying again about talking to someone. His excuse is "I'm not lying I'm just keeping things from you." I have tried to get him to understand that it hurts me. He doesn't realize that his lies are what caused me to lose my trust in him. How can I fix this? Some advice would be nice...I'm new to this
