Need advice

My fiance and I argued and he started work again today and just left without saying I love you or a hug. He hurt my feelings really bad and broke a promise about 2 weeks ago but he did apologize but we never got to fully discuss it because he started to not feel well and took care of him and he is 100 percent better now. But now my anxiety and depression have been at an all time high and he made a joke that triggered me and I just told him how I felt about it. He said I ruined the night I then went back and just said at some point we have to finish discussing this. He nodded his head and I thought we hashed it out and I went to sleep since I was really tired. He was getting ready and I asked him questions like if he needed help and he just shook his head. I asked him what he was looking for to help him find it and he said he was looking for nothing. He then left without saying bye and I called and asked him if this was the tone he wanted to set for the day and he hung up. He blocked my number. We have a son and he took my car to work. I get being frustrated and somties he gives me the silent treatment so I can react and we cam discuss me and why he was mad at me and whatever I wanted to talk about gets pushed aside. I don't know what to even do when he comes back. I did text him and told him he can't block my number because we have a child and thats just a no now. We aren't teenagers. I don't get why he can't just say I don't want to talk. He always does this where he gives me the silent treatment and its tough to parent this way and be a couple this way. So what should I do when he comes back ?
