I said I want a divorce, he won't talk now

I told my husband of 11 years I wanted a divorce a month ago. When I told him he broke down and cried on the floor for an hour before getting up and going to his computer room. We have been having issues for the whole 11yrs we have been together and I have been very vocal about my feelings throughout the relationship. We share a 5 yr old daughter together and since she's been born our relationship has gotten worse. The day after I told him I wanted a divorce he told me he isn't ready to talk about it. It's been a month and today I tried to ask him if he was ready to talk because I have SO much to say and I know he does too. I told him I want us to co-parent and be friends and still do things together as a family with our daughter from time to time. When I told him this he began to start crying uncontrollably. He once again went to his computer room and closed the door. I know I should be more sensitive to his feelings but it's been a month and we really need to talk. I think talking things out will clear the air about some things he may be fearing about the future with our daughter. He is known to shy away from hard conversations and tends to shut down and isolate. I don't know what to do. I know I shouldn't pressure him into talking but I am also having a hard time. We are in this weird limbo and we carry on day to day like nothing has even happened. It makes me feel uncomfortable not being able to share my thoughts, reasonings, and plans for the future. Before I told him about wanting to leave, we had plans to move from Florida where we currently live to another state at the end of 2027/early 2028. I plan to stay living together with him until we both find jobs in the same city in the same state and then go our separate ways then. It's the smart financial move for both of us. We can't stand Florida and if we separated here we both would never be able to afford to move out of this shit hole separately. I want to communicate all this with him but he says he can't bring himself to talk about it because it makes him physically unwell. I don't know what to do. Any advice would be great. Thank you in advance.
