Guys, thanks a lot for your information! Now, I remembered something: The only time she had feelings for me: Well, it was the time after I stopped calling her everyday... I stopped texting her every hour... I stopped proposing a dinner or a movie every weekend... I stopped being to close to her and gave her the opportunity to call me first. It had taken me a week or two after my ignorance before she told me about her feelings for me.
Should I do this again? It would maybe do the same effect, or else I'll be already on my way to moving on.
PS: Also, she told me the reason she had feelings for me was because I helped her and cared for her, with her personal problems. She was really down, sad and I was the only person that really showed that I cared for her. I showed I was worried about her.
