Little back story: Between 2011 and 2015 I was good friends with this girl who goes to my anime club. At one point I started to feelings for her and I admitted said feelings, however, she said she only saw me as a friend. Not want to ruin our friendship, I didn't push it. We did however flirt with each other but I knew not to push things. In September of 2014, some of the anime club members went to a con and I noticed she would say how shitting most of the other cosplayers were, and how the person HAD to know everything about the character before they could cosplay them. After this, I found the feelings I once had for her was gone, but continued flirting because that's the type of friendship we had. Then came August of 2015. We were at another con and for most of the weekend I was chatting with someone I had met the year before. We had hit it off so well that we got together. (Note that before every con I would say to the girl I was friends with that we might meet our partners there and she agreed it would be nice). However, I noticed that she didn't talk to me as much as we use to since going out with someone, to the point she'd talk to someone else more and when we did talk, she would drop our conversation to talk to someone else. At one point she even told me she did like me that way and regretted not saying yes to me as well as asking if she'd have a chance with me if my current relationship failed. I told my partner about this and how I was willing to drop her as a friend if we didn't sort it out and she offered to talk to my friend who said that I had dropped her as a friend the moment I started dating my partner. Naturally, I was highly annoyed by this since I had tried to talk to her more. I sent her a message telling her the reason as to why I wanted to drop her as a friend but was giving her a chance to save out friendship. Then came Tuesday, after the club, most of us head to a pub to chat for a while. She came up to me and asked me if I were okay. I asked her if we could talk about the last message I sent her and she replied with. "No, I don't want to talk about it." This hurt me of course, but at one last attempt to save our friendship I asked. "Can we at least text, even if it's once a week?" "No, because we can never go back to how we use to be." Was how she reply. At that moment, I gave up trying to save out friendship and walked away, sending her one last message telling her I no longer saw her as a friend. And that is the story of how I lost my best friend. There is more to it, but this is basically what happened. I just wanted to get if off my chest.
