My ex and I dated for almost 3 years. We lived 1700km far away from each other. Because he had a stable job, after 2 years together I moved to his city. My ex was a "religious" person that made me feel guilty about sex, and yet cheated on me. And now he's dating the girl (that I also knew), and rented the place that I helped him to buy. But, before all the bad things that he did to me, he was my best friend (and really good to me). The last time I saw him, we were still together. We never had the last talk. And after 1 year, I still can't move on and I'm truly depressed. I don't want him back, but sometimes I think that I need closure. Should I talk to him, after all this time? I really don't know what to do. I just wanna have peace.
