<human>: A little background on my girlfriend and I. We dated for three years in high school and continued that relationship into university. She dumped me after she told me that she was diagnosed as depressed and that she couldn't hold down a relationship.

Fast forward a few months we have come back into contact and are back into being physical, telling each other we love each other. When we go to my family get togethers or parties she doesn't say anything when people call her my girlfriend.

My concern is she has let someone into her life who she met when we were broken up. He and her hang out quite often but he has very short patience with her depression. He blames her depression on her family and me while it does not attribute to any of those things. He has called her depression an excuse for attention and calls her stuck up and attention seeking. He openly said he was going to beat up her father. He frequently has arguments with her about her family and harasses her and they stop talking. The next day he sends a text saying he is sorry and they are back to being friends and the cycle has continued about 6 times over the past month. He is extremely clingy, he will get angry when she doesnt answer his texts when she's at work and when shes out he thinks she is out seeing other guys. He has trying to convince her to stop seeing me.

I keep telling her that he needs to stop accepting his apologies but she just says that she is too naive and oblivious and that she doesn't want to lose what little friends she has. I have told her that he won't learn his lesson until she actually tells him to stop talking to her but he continues to harass her and she eventually accepts his apologies.

I am so frustrated right now but I am in no place to say anything since I'm not technically her boyfriend. I don't know what to say or do anymore. Any advice is greatly appreciated.

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend has a friend who constantly harasses her but she keeps accepting his apologies and I am worrying it is detrimental to her health.
