Was it my fault we stopped being friends?

i don't think it was your fault you stopped talking. it looks like you have strong feelings for this grl but they are not reciprocated. my advice to you would be try to forget about her as it looks like your friendship would never blossom into anything more that. find yourself someone who will love you back and treat you right. obviously this girl was not meant for you or you would be together. hope you find that special someone as there is one us there for us all
