My girlfriend has attempted suicide the day I broke up with her cause I understood she's just there for money.

I had a relation with a girl for 4 years. I got caught by my parents and they told me to shut everything off and tell her it's not gonna work. A year went by, I did that but I loved her too much so one day she texted me and tried to come back and I took her in. After that we were on and off and suddenly I started understanding that the girl just wants my parent's money and my brother lives abroad. She knows I have a little bit rich lifestyle so she started tagging along. I promised her that I'll marry her and we'll have kids but soon I started to realize that she's not the girl I love and she's just looking for money. Suddenly some fights happened in the last week and I told her that we'll end now. She asked me to meet her and I met her for one last time to end everything but she started crying and I let it go and I took her back in. She lied to me about somethings. I told her not to lie again but she lied again after that. I blocked her. 2 hours later I get the news from her smaller brother that she has drank phenyl and they're taking her to the hospital. I leave but on the way her married sister calls me and records our conversation where she tricked me into saying that because of break she might have done this. I feel like I'm being played in their hands now. I want a way out. I don't want my parents or hers to be dragged into this. Can I file a normal complaint in the police cause the next time I break up with her and if she does something like that, I want to be on the safer side? I don't want her parents to know about this. I just want my side safe guarded. I haven't done anything intimate with her. We've hugged and kissed maybe 2-3 times in 4 years.
