There's a guy at work that I've developed strong feelings for over the past months. He knows this and let me know very politely that he just wants to be friends. This was over a month ago and I still can't seem to get rid of my feelings. I think deep down I'm hoping he'll change his mind but I know it's not realistic to think this way. I still have feelings for him but I don't want to and am finding it hard to see him just as a friend. Any tips?
