My ex is silencing me about telling the truth to his affair partner
My ex left me for someonelse without any notice. I went to Germany with him not knowing that he was already living with another girl. And the next day of the trip he blocked me and told me to never call. I was away for work like 6 months and he found this girl and they dissapear together. But he tried to send messages , emails , telegrams… We were talking time to time and then we started to sleep together and he was waking up middle of the night , saying that the girl watches the cameras and leaving me . So he was just sleeping and leaving. 3 months ago i realised that he changed his country , one day he told me that the girl did not go with him but then said that it is too much info to give . And around 3 weeks ago we were talking and we had a fight . Later one of my friends saw his photo in his new country with that girl and she looked pregnant to me but i am not sure . Anyway he keeps me silent about this and he afraids i will tell everyone , which means that he will lose money or something important for him.
What do i do ?
