Mind darkened by violence

I want to hurt them I'm sick of them hurting her! Ganging up on her I want to see them feel pain! They inflict so much ****ing pain on her they deserve it all! The monster I have been trying to hold back is escaping more and more everyday. I can't let this control me but it gets harder and harder everyday

If you do something stupid, you'll be making it worse for her.

It seems critical that you to talk to a doctor.

Even super heroes have partners. James Bond has Q, Batman has Alfred, Ironman has Jarvis and Pepper...

There's no shame in having backup, assemble your team and decide the best course of action moving forward.

All that you will achieve is ending up in jail.

I know how hard it can be in these situations, but believe me you have to be a smarter man about these things. Violence feels good short term. Violence long term only brings you and your loved ones pain.

If you want to protect your GF then be smarter about it. Do whatever it takes to be able to support her financially and ask her to move in with you.
Then between you and her, you can both work on improving your lives together.

One other thing is, (I'm not aware of your situation or hers so no offence intended here)
some people are drawn towards drama. Some actually prefer dramas to a life of happiness and peace. Be aware of this.
I've learned in a lot of cases the drama and conflicts in most situations can be avoided by making the right decisions.

Anyways, good luck with it, I hope things improve for you both.

If applicable, perhaps you could take the matter to the police.

Yes, I agree with the above. Work through the right channels and be smarter. Think what kind of person your girlfriend needs in her life; not like for like. I can empathize with you. I've had to deal with this from the inside: my own family, my mother!

Thank you for all the tips I am not going to do anything I was just furious when I wrote this I'm sorry for the inconvenience..
