I forget if you've turned down the idea of marriage counseling or not. If you want conversation, sometimes the best environment is a neutral site in a counselor's office, where a 3rd party will attempt to drive the conversation and keep it going. I have this problem in my M since my W "doesn't like" to talk. We start a conversation - it ends a minute later unless I carry it with more questions or comments. You can't "get away with this" in a counselor's office.
Other than that, I think you need to relax and keep talking to your H when you want to.
