Am I a bad person for liking this girl?

My last year of college I met this wonderful girl, who made me feel things I haven't before. For the first time in my life I felt like I was capable of being loved, the way she treated me nicely instead of taking advantage of me. She had her own problems, suffering from anxiety and severe depression. She had an abusive boyfriend, who almost pushed her to the point of suicide on multiple occasions. I broke up their relationship. Some time later my friendship with her deteriorated, I tried to both be her friend, but she already knew I was interested in her myself. She pushed me away, and severed all contact with me. I asked around why, and apparently my messaging once a week became annoying to her. She had many new boyfriends since, and it always hurts me because I know I can never be loved the way she loves those other guys. I still have mutual friends who tell me what's going on in her life, even though she want's nothing to do with me a year after we last spoke. I have had thoughts of ending my life to make the hurting of her absence stop. I just feel so incomplete, and empty knowing we can't ever be together. I've even resigned myself to the fact that no one else can love me, and it would be better to avoid any future involvement in romantic relationships with anyone else because no one else has treated me as nicely. I have good friends who did convince me she isn't the only light in my life, but she was such an important light I can't feel whole again without her.
