The end of a friendship

I can't believe that today is the end..... The end of once was a very good friendship between my soon-to-be ex. His girlfriend has him soo wrapped and made sure that she got him away from me, that she continues to lie to him about me..
Today after work, I was leaving and noticed an empty spot of which I thought Kelly was parked, and whispered "Thank god she is gone". Then I proceeded to leave and noticed another bus driver walking to her car, joking around I pretend to drive straight to her. I pulled over and asked a quick question and did not notice that Kelly was actually parked right there and she was in her car. Well she was on the phone with Chris and she proceeded to tell him that I was blocking her in..... BULLSHIT... I thought she was gone and did not notice her until Aida backed away and I said to my self" OH SHIT, she is still here." As I looked at her she chucked me the bird so I chucked it back at her and said fuck you bitch (not loud because Joshua was in the car).
She then said to Chris OMG... she just chucked me the bird and said fuck you bitch.
So when I got home, Chris was there and he was very upset with me.. Don't know why but he was, I finally got it out of him and he said because I chucked Kelly the bird.... WELL hello, I only did what he told me to do before,, give it right back at her.....so I did.

Well she has lied so much to him saying that I blocked her in and I don't know why she is chucking me the bird. He ACTUALLY believes her.
We got into a huge argument and he no longer wants to be friends anymore..
He stills thinks I am the one who is lying to him. I am very hurt that someone who was once a very good friend, wants nothing to do with me... but no matter what I say, he will not believe me.
I can't believe that I still cry myself to sleep every night because of what she does to me at work, and I said nothing to Chris, but she has no problem saying things to Chris about me.
Well no all the damage is done and there is no going back. No husband and no good friend.
It was funny when the boys told me yesterday that they meet Kelly, I could not believe that Chris would do that to me soo soon, but all I could think of is "BOY DO I MISS MY FRIEND"
Chris kept on asking me whats on my mind right this second and I could not tell him...
I DO AND WILL MISS MY GOOD FRIEND...

Good bye for now...
