I'm in relationship with a guy since 4 years. He cheated on me with my bestfriend when our relationship was 4 to 5 months old. He regretted it and cried and said it was a mistake and he would never do it again. I forgave him. But it's been a long time since he cheated, he has proved me in many ways that he would never cheat on me, we are in a long distance relationship and we meet every month, he texts me all the time, turns on his location for me, video calls me, sends me pictures when I ask for it, receives my call, but I still can't get that off my head that he cheated on me once, even if it's been 4 years, the fact that he cheated on me with my bestfriend still kills me, well she's not my (bestfriend) anymore and she didn't even feel sorry for once. How do I get to trust my boyfriend again? He gave me his mobile phone, with no hesitation, told me his password for all the social media's. But I am still traumatized by the fact that he cheated on me. Help please 🥺😭
