Should I confront my ex about his cheating?
Back in January me and my ex started dating again. We'd broken up 4 months previously but after the new year he said he wanted to start dating me again so we got back together. At that point we both knew that I would have to leave the country for good in 6 months but we tried to just have an amazing last few months together. We eventually decided that when I left we would have a long-distance relationship. The thought of breaking up with him again just killed me. So anyway I went to stay with him right before I left the country. When he was at work one day, I decided to use his internet and his email account automatically opened up. I know that it may seem like a bad thing to do but I thought that if we were to embark on this long-distance relationship only seeing each other twice a year or so then I needed to know that he was a solid guy. I didn't want to invest everything in him only to have my heart broken. So I went through his emails. To cut a long story short I found out he'd been messaging girls in other countries sending them flirtatious messages. He even met up with one of the girls when he went on holiday to her country despite the fact he was due to meet me the next day. He was cheating on me. I have no proof that he did anything sexual with these girls but the fact that he went out of his way to create an online dating profile to meet other girls suggests he was intending to sleep with them. I was devastated. After a trivial argument the next day, I packed my bags to leave his place and I didn't see him again before I left. I never told him that I discovered he'd been cheating. At that time I was just a complete wreck. I had so many emotions going through me that I didn't know what to do. I was livid, hurt, heartbroken and scared of who this person actually was. I just decided to be cautious and get myself out of there asap without confronting him. But even now I still find myself wondering every single day about why he did it. So many questions keep going through my head like why bother getting back together with me if he felt the relationship was bad enough to cheat on me? Why bother going to the effort of calling me everyday (we had a long-distance relationship in the same country too) if he had girls he was messaging? I just can't get my head around the fact that he said he wanted to be with me no matter what yet at the same time was out there searching for other girls. It absolutely kills me. I just want to know WHY! Does this mean he didn't like me at all the whole time? Was our relationship not real? At the moment I feel like he's got off scott-free. He must feel like he's got away with his cheating.
So my question is should I confront him about it or not?
