It's just a starting point. I remember a man who had similar problems to yours. He could not talk to his wife in person, but was able to do very well over the telephone. Another fellow used e-mail to share with his wife. Eventually they all were able to chat in person.
Communication takes practice.
Secondly, don't assume that your wife does not want to hear your thoughts. Many of us think that our thoughts would not be of interest to another person. In an intimate relationship, connection is more important than the information. The talking itself is more important what you say. Even the most mundane thought you have or the most insignificant feeling can be shared and appreciated as a form of connection.
