What does he mean?!

So me and my husband got married in feb. we’ve been together 5 years total. We’ve had issues like any other relationship. These last couple weeks things have gotten worse and we’re fighting almost every day. I keep asking him why he doesn’t just leave me and why he just can’t say it. He said “Im not leaving you, but I don’t think we should be together” but that literally makes so fucking sense to me at all. What do I do?

Edit: he doesn’t even talk to me, or look at me, or have sex with me anymore. We don’t do anything together anymore. And no I’m not innocent in how we got this way. But I still want to be together.
