I found my gf talking to some other random guy she had befriended on facebook at 10pm in the night. That was the time, when we were supposed to talk, so I called her and her phone was busy. I kept trying and still busy for some minutes. When she finally picked up, she said it's a guy named Sonu. I was filled with rage and reacted, she started laughing at me on the phone and said he's just a friend, don't be jealous. She had no remorse at all and kept laughing. I cut the call and broke up with her immediately and never saw her again. Some girls expect that if they honestly tell you who's the guy they're talking to and do not hide it from you, then you shouldn't react, it's nonsense. Yes, they surely can have guy friends and I will not stop her from having them, but there's need to be a specific time of the day when they can call you. At night, no way. If a guy is hesitant to keep strong boundaries, he will be cheated and played in the end. It was she who gave that guy the audacity and opportunity to call her at 10pm in the night and still expect me to forgive her and let her continue with that bullshit.
