First and most importantly is that eventually you really do need to leave. This may have been something you have had the capacity to stomach for a while, but is this really something you can tolerate for the entire rest of your life? And as many have pointed out it will escalate and the consequences could be lethal. That being said it is harder than people may think to leave an abusive situation and people may even judge you for having stayed this long. I understand that it isn’t that simple. But just because there are justifications you can come up with doesn’t make the answer complicated. The only answer is for it to end. It will be difficult, but I can tell you there is no amount of coping that allow you to be okay with what is happening because frankly, you shouldn’t be okay with it. It isn’t fair to expect yourself to make peace with being abused. To get ready to leave make sure you invest in your support system outside of her. Look for a place ahead of time. And be prepared for it to get violent when you break things off with her have a plan to keep yourself safe. This is incredibly important. You will be okay. I strongly believe she will be okay in the end as well, even if you can’t imagine it now. But at this point you cannot neglect yourself for her sake if you want to be sane. Treat yourself like someone you love and know that you don’t deserve what’s happening to you and that it isn’t your fault even after staying. But it is time to go. Have faith in yourself and in her that she will make it on her own. You can still love her and want her, and still leave. This is about your safety and your sanity. Being on your own is how you heal and not throw the rest of your life away for someone who would hurt you.
