Sorry if this is a little long, I need to type the whole story out. 4 years ago when I was a freshman in college I met this girl in one of my classes that I did homework with all the time. At the time I was very awkward and didn’t have any confidence or hobbies or sense of self so I never would’ve dreamed of asking her out. She was cute and friendly and I thought she was way out of my league. Over the next 3 years of college we became close friends. I developed some confidence and interests and became a way happier person, but I always had a secret crush on this girl and I thought she didn’t like me. A couple months before we graduated, I found out that she had liked me for quite a while. I quickly told her how I felt and we spent the last 2 months together which was amazing. I asked her to do long distance, since we were moving 10 hours from each other. she said no, totally understandably since it would’ve been very tough on both of us. I moved away, slightly heartbroken but ready to move on and met a great girl on Hinge. I’ve been seeing her for a couple months now and like everything about her, we have so much in common and I really do think that we are a better match than me and the girl from college ever were. But still, I spend so much time thinking about the girl from college. What I should’ve said or done differently, all the moments and signs where I should’ve told her how I felt but was too scared. I know nothings ever gonna happen between us and I don’t want it to, but all the nostalgia and history of our relationship is eating at me and I’m having so much trouble not thinking about her. I thought it would fade with time but it’s been 3 months now without contacting her and it isn’t going away. Any advice?
