<human>: Can you give me a shortened version of the text?

First of all, I am 21, she is 23, we have been together for just over a year now. 

She has dated her fair share of crazy men, and I often hear from her friends things like "you are the first decent guy she's dated". I also have the approval from her family, and I have heard things like "you are the first guy she's brought home who we actually like". She also has issues with self-worth and what to expect in a relationship. This makes me think that the other guys have been abusive/maladjusted. 

Every once in a while, one of them will attempt to contact her through the internet and her cell phone. I am not entirely sure who it is who is bothering her, nor am I sure if it is the same person every time. 

Every time she is contacted, she doesn't reply, but still becomes extremely upset. She is in the process of filing a restraining order and changing her cell phone number. 

What can I do to help in this situation? What are some ways I can comfort her and help her to feel secure? Are there any tactics for getting these "crazy ex" types off her back?

Thanks for any help. I wasn't sure what subreddit this would be most appropriate in, so I hope it's ok here.
<bot>: GF is being hassled by her ex, and she doesn't seem comfortable talking about it. What can I do to help? What's the best way to work through this together?
