Do I need to tell a girl that unfortunate incidents in her life were karma?
Do you really believe that everything that happens to her is karma?
Yes, only those bad things that happened to her though. She is a psycho
While some people can be very frustrating and can be very hard to deal with, expecting bad things to happen to them is not a good way to maintain relationships. If it's still possible to fix your treatment with this person I would suggest that you do so. You would not want other people to plot against you or to wish something bad to happen to you, do you?
I will treat her the way she treats me. She's the one who should stay away from me.
The both of you already suffered enough, do you think it's fair to keep trying to keep the cycle alive? How about just moving forward, and to not judge anymore to spare all the negative feelings?
