End of a Friendship

Tonight i had a blow up with a friend i thought i could trust. Not everyone can be trusted and i found that out with this particular person. I get online , they send me an IM basically saying what is wrong with me, why cant i take the time to give this person a call right after i told them i have stuff going on. I had to stand up for my self. I told this person i have a life and it doesnt revolve around my friends, i dont think i should feel obligated to stop my life and take a call. This person has their own things going on and i dont expect them to call me. So after taking a stand , i deleted this person from my contacts, and we are no longer friends. This person has been disrespectful and i dont need that kind of friend in my life. I rather have no friends then be friends with someone like that. When i started talking to this person, my heart started beating really fast like i was about to have panic attack, when you want to feel good about doing something like me standing up to this person, i dont want to feel i'm out of breath. i guess its because i've never stood up for myself before. I learned alot from this person, i noticed the things this person has done and i've stopped it. I feel really good, but still hurting by what this person said. Life goes on , i'm not going to fret over it. Hopefully i'll find that ideal friend, who wont controll me, bully me, or use me. Time will tell.
