GAD is ruining my relationship

My anxiety has been through the roof lately. My husband and I are planning a really big move to Hawaii. It’s waaaaay harder than I thought it would be. It hasn’t even been a year yet and I’m falling apart. I fought with him until 2 am last night because I was having an anxiety attack. I say things I don’t mean including “I’m leaving, I don’t know why I got myself into this, maybe I should just leave” I feel so awful that I’m pushing him away, but my over emoting and his lack there of causing so many breakdowns and so much resentment. It seems like every single thing he does for me is so wrong. I feel like all of our romance and happiness is gone, but I think it’s my fault for not being able to handle my anxiety.
