We've been together over four years now. Got engaged about a year ago. I love her with all of my heart. I've gone to therapy a few times to help with things but I feel like it's just not enough. We're at a point where I just don't know what to do. I want to help but I don't know how. So I've just tried being loving and supportive. Over the last year though, it's just gotten worse and worse. We argue every day. Neither of us are in a good place anymore. I can't comprehend how she feels and it's so hard for me not to overreact anymore when she does. I do something that upsets her and she lashes out at me and I feel like if I don't stand up for myself now then I never will. But when I stand up for myself, I just get defensive and make things worse. She wants me to clam her down and not overreact but it's just so hard to do that because my automatic reaction is to lash out back. If I don't stand up for myself, I feel like I'm just constantly giving in and walking on eggshells 24/7. But when I do, I'm just defensive trying to prove I'm right. Any advice is appreciated as I don't know what to do anymore.  Thank you in advance.
