Honestly, this was my exact story some years back, his married ex calls him even by 2am, whenever I tried to talk to him it turns out to quarrels, it made me feel like I was insane and insecure, I mean good men are hard to come by like they said, so I endured. He promised me all they talk about is random gist, sometimes he answers her call in my presence but after one heated argument I asked him to choose btw me or her and he said me but then I started noticing he doesn’t talk or mention her name anymore, I was happy but I noticed he was always holding his phone even in the bathroom, one day he forgot and her chats was just pouring in, this was around 10pm, I asked him at first he lied but later told me he never stopped talking to her...well not trying to praise myself here but I’m the type that would hardly get jealous but that was how he made me feel, insecure...we are no longer together but I will advise to talk to him once more else please leave, you are too beautiful and you deserve peace...
