I had a huge crush on a girl in my college but she was with someone else. I created misunderstandings between them and pretended to understand her whenever she was low. Eventually, the misunderstandings grew so much that they broke up. I proposed to her after 3 months. She is my girlfriend for 5 years now and still has no idea that it was me who created problems. I feel really bad about it but the heart wants what it wants.
