Recently, I Broke up With My Girlfriend Because She Was Cold, but She Became Yandere

My girlfriend has been cold lately.When we first started dating, we were such a couple that everyone around us was amazed, but now that a year has passed, she refuses to go on dates, kiss me, nor have s*x with me, and even refrains from holding my hand.In addition, she repeatedly abuses me, her boyfriend.How can this be called a relationship?I was so pissed off that I asked her to break up with me.Then, she started acting strange.She turned into a yandere!Will I be able to escape this woman?
