<human>: Give me the gist of the text in a nutshell

My girlfriend is in a deep depression and we are currently not seeing each others. We chat over skype and whatsapp all day. But we are on something like a break, because she just can't feel anything for anyone currently. I am ok with that. If that the thing is she needs to get out of her Depression i can deal with that. 

But as soon as her depression started she started seeing an other guy. She assured me they are just friends and she is not attracted to him. She told me that she can forget her sad life when she is with someone who is not that close to her. And i had my sorrows but again, i said to myself if that's the thing she needs, its ok.

But she keeped seeting him, she went to his place, they watched movies and she was there for about 10 hours. After that she told me she's affraid he's faling in love with her. This was a week ago. This weekend he told her that he is interessted in more, when she spent her saturday at his place. All that while she does not want to meet me. I feel like I am only good enough when she's borred. 

She assured me that she is not attracted to him. I do believe her. But she is still meeting him today. I can't forbid that,  since we'r on something like a break. But we agreed to do nothing which would destroy a future together. 
I already told her that i would have to quit any contact if she would sleep over at his place. I could not handle the pain, him beeing with her, even she feels nothing. I want to be the one she spends time with. I would love to tell her how i feel. But she has enough problems with herself and i feel she would not even care. 

What should I do? I am in a abusive relationship!
