Not sure if this is the right place to post, but here I go.

Is this a particularly cruel way to break up with someone, or is it something I should get used to.

I got a msg on my phone after school saying I was dumped, she didn't want a relationship anymore. Then she ignores my calls, so I go down to her work (she was working) but she won't come out of the kitchen and see me. So one of the guys lets me go around back and she agrees to come tealk. She tells me, emotionless as a rock, that she doesn't feel anything for me anymore. So I get up and leave, and later she phone msgs me again saying she has been crying all night, and holding a knife to her wrist. So she comes to talk, and she takes me to the beach at night and we sit with the waves crashing a few metres ahead, and she tells me she loves me and wants to be with me, she just needs to sort shit out and she'll come tell me tomorrow that she wants me. We make out, then I go home and she goes to a party and gets with some guy. Then she comes to my house the next day and tells me that she cheated on me, and that I'm dumped again. Emotionless, as with the first time. Didn't care at all.

All 1 week before major end of highschool exams.

Is that harsh? Or do I have to get used to shit like that.
