Girlfriend always arguing

I’m so far from over my relationship. I have given it chance after chance after chance to only be disappointed after 8 years of on and off relationship with my girlfriend. I had anxiety knowing she was getting work off soon.

She has taken 2 weeks off work, and it’s been the most horrible shittest time. She has fought with me every single day since the day she started her holiday. Over every little thing. We are meant to be going away this weekend down south ( 3 hour drive ) with her family and I’m honestly dreading it..

Everything I do or say is wrong…

She takes no responsibility for how she treats me.

Last time I left I was sure I was done but then all the promising to change and how sorry she was she started sending me.

Through the 5 weeks we werent together she didn’t fight with me once but as soon as I forgave her and let her back in my house within 1 day she was back at being nasty to me.

I’m out of things to do… I don’t know what to do anymore. She spoke to me like shit today infront of her family and it was so embarrassing .. but tells me I’m just being pathetic .. telling me everything I do wrong.

I need help? Or advice? I physically can’t do it anymore :( anyone else been in a relationship like this?
