We were each other's first loves. She was 16 when I met her and I was 19. She is now 18 and I am 21.We were with each other for 2 years before we broke up a month ago. I was the first man she ever had slept with and although she wasn't the first woman I slept with she was my first girlfriend and first love. we spent every day together. We were immersed in each other's lives. In the beginning everything was fun. Nothing was boring and we fell deeply in love after 6 months of dating. I never told her I loved her until about 6-7 months in, because honestly I didn't love her and I didn't know what love felt like because I had never felt it before. But when I told her I truly meant it. I remember looking into her eyes and holding her and knowing how amazing love is, to really love somebody for who they are, it was the greatest feeling I ever felt. We got to know each other's families really well and I was always spending time with her family as she did with mine. I picked her up from school every day. There wasn't a day that went by that I didn't see her beautiful face. I remember about a year in we just looked at each other and cried knowing how much wee loved each other. So the last 4 months is where things took a turn. I was struggling with an addiction to internet pornography. She knew that I had struggled in the past with it and hated that fact. When I came to grips with the fact that I had a problem, about early February, I told her thinking she would back me and support me. I was committed to sopping for the sake of our love and sex life. But she took the easy way out and dumped me. A month went by and despite the fact that she dumped me she still wanted to have sex. I didn't want to be broken up but I couldn't argue with her at the time, I felt as if she made that decision and in the mean time I would work on myself. We had sex for the following two months until about a month and a half ago she told me that we shouldn't talk anymore. I broke down and asked her why she wanted this. To make a long story short, she has moved on, or so it seems, and is dating a new guy now. He's richer and more physically fit than I am and is more popular on social media (instagram). She's posted pictures of them kissing, and seeming so happy. The last two times I saw her since she's been dating this new guy I broke down in tears. I tried to keep my cool but I truly love this girl and she means so much to me. I have too many fond memories together. She sat there and watched me cry but seemed as if she had no remorse. I told her all my feelings including how much I love her and how much I have realized I have loved her. She only says "why couldn't you feel this way when we were together". She gave me a last hug and kiss on the neck and left my car 2 weeks ago and that was the last time I saw her. Everyday I have been thinking of her. She seems happy with this new guy now and I just can't understand how she had moved on so quick. I am stuck here so deeply hurt but deeply in love with her, and all I can think about is if she still loves me deep down inside. We were eachothers first love and absolutely crazy about each other, sometimes more her than me, and now it feels like my other half is gone and taken from me. What is my girlfriend thinking? If I don't contact her will it work? I feel like I haven't given her the time and space to even think about missing me. What should I do?
