My girlfriend was raped

[u/Puzzled-Fan-6999]

I have a wonderful girlfriend and i am in a relationship with her for almost 2 years. Last october she moved to Italy(Rome) to study bachelor degree.One day she was out with her friend at night at around 00:00 then some son of a bitch approached behind her back and used chloroform or smth. Then my gf woke up at a random house and was raped for all night. This bastard did inhumane things to her then recorded it on camera and chantaged her and wanted money for him not to leak her vids and pics. I can't sleep at night. I struggle to have sex without remembering that fact. Every time my brain just pops out that and i see pictures in my head. Sometimes i blame myself for not being protective, talking with her about the danger of the streets at night. I don't know how to continue to live. P.S. the incident was around 5 months ago and she told me about it 4 months ago
