Please help

I have been with my boyfriend for 2 years. We're at that part of our relationship where we constantly fight. I try to talk to him and tell him that I don't feel loved or appreciated and he says he's always too tired. Today he told something that just broke my heart. I asked him what I needed to do to make this work because I love him and he told me "just leave me alone. That's what will make me happy" how could he say this to me. We just moved in together and I'm starting to think it was a huge mistake. I'm just so confused because I love him and I understand we can both be clingy to each other but I've been through a lot in my past with love and being hurt by people closest to me and I depend on that feeling of being loved. Im so depressed and feel like I need answers. Please help. Anything will help.
