Was It The Right Choice?

After all I've been through with my friend, I decided to cut ties with her.

When I first met her, she was the jolly girl I knew and saw. We kind of became friends, but as time passes you can see her real skin peeling off.

She was your typical rebel kid, and she was dependent on me most of the time. Some of her homeworks, her projects, listening to her family problems, to also make her score higher on real exams (requiring cheating). I've done so much for her, and I can't even expect one thing from her back.

When I confonted her about this matter, she cussed me. "F*** you. I am not dependent on you and ***** (My other friend)." F*** me? She continued to say any cuss words, which is ironic as she was of religion. I tried to ignore her messages until she calmed down. But I was too furious.

The next day I ignored her.

Then months later, we're still ignoring each other. I don't have any more best friend.

Everyday, I regretted my actions. "Should I have understand her position? Should I apologize? Should I this Should I that?"

This thought is eating me alive everyday.

(I am currently writing an apology letter, but I'm scared for the result. I am thinking of not sending it until summer break. I can't face her.)

Is unfriending her the wrong choice?
