I (23M) am unable to accommodate my girlfriend's(22F) mental health disability. How do I end our relationship?

My partner has Bipolar Disorder, and with that comes a lot of unpredictable emotional episodes and needs from me that I am unable to accommodate. I've tried to be patient, but I feel burnt out. Here's more of a back story:<br><br>I was in a relationship with my ex before I met my current girlfriend. After a year of mentally and verbally abusive behaviour from my ex, I broke up with her. It was followed by a stalking event which was horrific at the time. I eventually moved to a different town with a new job. I was perfectly happy with the new place and job, but it was difficult to make new friends. So I tried tinder; I met my girlfriend. She was the kindest person I had ever met and I got smitten really quickly. She was from my town, but living in a different town for her job. She used to visit me often and I enjoyed our time together. I thought she was perfect. After a year of dating, she decided to move in together with me and then she told me about her Bipolar disorder.<br><br>Over the past year, I have tried to accommodate her needs. I have been patient and supportive. But things have been going downhill for some months now. She can sometimes be really mean to me sometimes and has even slapped me once. Then she's sorry and promises not to happen again. But it does. I don't know what to do. I feel burnt out and I can't tolerate living with her anymore. But I don't want to end our relationship as I love her a lot. I never want to hurt her. I am struggling to find a middle ground.<br><br>My plan is to change our living situation - we used to live in a apartment, but we are moving into a house with many more rooms. I want to have a separate bedroom and office for myself. But I think this is just a temporary solution. I feel like I'm turning into a bad person and I do not want that. <br><br>I am sorry if this is a really long post. I just wanted to tell the whole story and see what you guys think I should do.<br><br>TLDR: I am struggling to accommodate my partner with mental health needs and want to end our relationship. What should I do?<br><br>&#x200B;<br><br>UPDATE: Thank you for all your support. It's really been helpful to read so many comments. I have decided to end the relationship. I also spoke to my girlfriend about the issues I have been having and she immediately apologised for it. I will be supportive of her and help her find new accomodation from my own place. The plan is to move out in a few months. I also asked her to seek professional help for her condition and to have a psych evaluation. I hope everything works out in the end and she will be okay.
