This is a semi common thing to happen. Often while dating women will give men a lot of recreational companionship (i.e. Doing things together) and men will engage in conversation with women because they are very engaged.
After marriage women tend to pull back on the recreational companionship, and men tend to pull back on communication.
One thing to try would be to *do* activities with your H that he enjoys -- golfing, tennis, going to sporting events, whatever it is. Often men don't like sitting around talking but if they are doing something they will also talk.
For example, you will probably have more luck discussing finances if you're out for a walk versus sitting at the kitchen table.
Experiment with no heavy conversation unless there is an activity involved and see where that takes you. Even doing a puzzle together may be enough
