I just don’t understand

I’ve never posted before but I feel I need to get some stuff off my chest about my relationship. My girlfriend and I have been dating for over two years now, and we have many struggles with communication during arguments. I feel as though I am constantly wrong whether it be my wording or my feelings she just never likes what I have to say. I feel like I try so hard to come from a calm and logical position about things but her high emotions make it impossible to really talk things through. She tends to yell at me and call me pretty brutal names when an argument arises, my character has been attacked countless times and I’ve started to feel quite bad about who I am because her words stick even though I tell myself she doesn’t really mean it and that she’s just worked up. Stonewalling is a huge issue with us when she gets too upset she ignores me and tells me to screw off and not talk to her anymore it hurts because I only want us to figure things out. I love her I really do but I really don’t know if I should stay in this relationship.
