How do I get my ex gf to leave me alone?

[Dwayne]

We dated for 3 years until she left me for someone else. The beak up was civil at first until she started spreading lies about me, so I cut al contact with her and decided to move on with my life. About 7 months later I found a girl I really liked. The day we started dating my ex added my new gf on fb. Then was saying mean things about her to my freinds, saying "I downgraded" and shit. Which basically lead to us breaking up a few months later. Now the other day my exs best freind followed me on twitter then after I accepted it unfollowed me. Obvious sign she is having her freinds snoop. Why tho? I just want her to leave me be. Then I heard from a mutual freind that she was saying that one day she wanted to see me again. I don't want that. She is still dating the guy she left me for but still stalks my shot. Why?

You could cut off all social networking and make sure the next girl you date knows your ex is a PSYCHO BlTCH! Or just creat new profiles and be very cautious of who you add

Her new guy is just to fill a void in her life and she still has feelings for you. Send her a message clearly stating that you have no intentions of ever talking to her again and that you wish to have her stop doing the things she is doing. She needs to be set straight.

Guess you could try telling her boyfriend to make her back off .. Or show him this.
To me, she just sounds like a derriere that doesn't want someone who she dumped, to end up having a better life with someone else. Makes sense doesn't it?
If i were you, I'd really tell her to **** off and harshly insult her.
That is if you haven't told her to stop already....

Her new guy is just to be there till the day she hopes that you get back with her. Just cut her off and dont even worry about what is going on with her. I think you should just keepin on keepin on and worry about your life and not hers. If she stalks your s h i t, let her. She cant stop you from doin anything you want to do, so just live your life and let her do what she does. All she is doing is hurting herself, and goin to other people and your social media just to see if you miss her. Its pointless... Make new social networking accounts and make sure she cant see them. and let her look at the old ones. Do what you do. She will eventually get tired of chasing after someone who isnt chasing her back. Just keep doin what your doin in life and be yourself and not a worried person that their ex is gonna keep stalkin them. Be you.
