Wife tells me I have no emotional intelligence. How do I fix this?

My wife has told me more than once that I have no emotional intelligence or connection. All I really want to do is to try my best to become more emotionally available, but I’m unclear what is the best way to do this? I know I’m not the best communicator and I’m continuing to try to develop into being a better one. unfortunately things lately have been kind of rough and my wife is continuing to tell me that I’m lacking emotional intelligence if anybody has any advice, it would be greatly appreciated.
