Mixed signals?

I've just been diagnosed with depression. My relationship with my fiancé has majorly been affected by it. I know I should have got help sooner but I didn't and it might have been too late now. Hes now told me we aren't a couple. We did agree that we should spend time apart but he told me he wanted me to fight for him. Even though I moved out, because I thought it was the right thing to do(I now know it wasn't) in my mind, I moved out to give him his space, he could do what he wanted without me complaining. I complained about everything he did. On his phone too much I felt like I bored him. He had a day off he wanted to meet with friends and I'd complain I'd never see him. I wanted too much from him. I used to talk to him all the time when I was sad but I guess I did it too much. He would start to snap at me and tell me to stop being negative all the time, he would even tell me what I should be feeling. I stopped talking to him and that was when it got worse. He would know and get annoyed. I moved out because I thought if I wasn't there then I couldn't put so much pressure on him. He says me moving out was loud and clear. Saying I should have fought for him. I started texting him. Telling him what I thought was the right things but that annoyed him more because he says I won't leave him alone. I told him I thought he wanted me to fight for him and he says not now it's to late. I know if I didn't text him he would have said I didn't want him. I'm so confused! I don't know what I'm suppose to do? I think he wants to end it, only because of the texts he's sent but he doesn't want to be the one to do it. He's said we're not a couple but I don't know what we are anymore. I know me being sad and being negative all the time has got to him and he doesn't think I love him because I'm never happy. I love him so much but don't know how to be happy anymore right now. My depression has made me lose the one thing that really matters to me

Sorry for your pain. It does not sound to me like you had much of a relationship anyway. If you are having major depression, then you need to take care of you. This may not be a good time to bring a bf into the picture.
Are you in therapy? It has helped me so much. I cannot say enough good about getting psychotherapy. Be easy with yourself. Don't put pressure on yourself. It is hard to make decisions when your thinking is not clear.
Time away from your bf is probably a good thing at this time. Personally, I believe before there can be a romance, there needs to be a friendship.
Give yourself a hug. You deserve it.

We have been together for 5 years, engaged for 3 of them. We used to be best friends. That's why it's so hard because I don't have my best friend to tell all my problems to. I start therapy soon. I just feel more lost because I don't have my best friend or partner right now and he used to be the one thing that helped me feel better.
