Songs make me maintain my love to her

Normally, I don't think about her in that way, loving. But whenever I hear a sense-making song about love of which story they sing is just like mine just think about going back to her, even though I usually don't think about her or love her. I remember the good old days with her, having the same feeling as I used to have, but without songs, it's impossible. Tried to go back to her, but I was the one who stopped feeling things to her. I do not know the reason, if it's because she was so jeolus or something, but all these songs make my mind about her. I just want to cry whenever I listen to those good songs and also think about going back. But it's also a bad habit, people say, just 'loving' one and then stop loving. Well, I am not the one who stops loving at all. I don't say that I should stop love, or make a plan about it. But even if I want to go back to her, I think it will go to shit again, as it did like a week ago. I am a bad person for just "stopping loving", right? Oh, and also, the main question is that is it normal to start feeling things to the one, to the desired one whenever you start listening those?
