Rest of the story
He told me that his "colleagues" from the office downloaded Tinder on his phone to have fun. I have not really used it so I was a bit unsure what to check about it but the pure reality was right under my nose that he had it. He claimed that he just gave his phone to those 2 guys from the office to do whatever they pleased to do with his phone and in this way he was having a conversation with them, making friends in this very pathetic way as I were to believe. At that moment I wanted to believe him. He showed me the matches and the conversations with 2 people that he actually knows from that ####### office and one woman from Canada that he asked to "have a coffee with" while he will be in Canada and she did not reply to him. He was like "If I wanted to cheat on you why would I have invited you to show you the places that matter for me, why would I make an effort about you?" and I wanted to be convinced. But when I think about it again it is not okay at all.
