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?
