When to let go?

I need some sort of guidance. Everyday seems like a chore now. Fights every day. Unhappy but scared to lose him. I just need to know when to let go. I don’t wanna get too into detail but it’s like he’s 2 different people. I honestly feel like my SO hates me. I don’t feel loved anymore. But I love him with everything I have. But I just don’t know what to do. I honestly feel like he picks fights with me on purpose and idk why. Just don’t know what to do anymore.. I left everything I knew for this man. Im 1.5 hours from my home town and my family. And I can’t just up and leave. I usually would have to wait until my moms off work to come get me. And by then I’ve talked myself out of leaving. Idk what to do anymore...

Update.

Our most recent fight was today and it was because I had tumblr downloaded on my phone. I only follow rave pages and pages about hair and quotes. And he accused me of trying to hide it or that it was for dating.
