A situation with hidden feelings and avoiding issues is a recipe for marital disaster, and it is a sad situation that this has happened so soon after your marriage.
There are any number of approaches to try to change this situation. The success of changing a situation like this is going to depend on how obstinate and distant your husband is and how much time you and your husband are willing to sit with each other to provide time to communicate.
Spending time together without TV and without getting high or drunk and without distractions from children or friends or phone calls is important to enhancing communication. You could have a cup of tea or coffee, and you can even play some table games that don't take too much concentration. Allow the conversation to develop. Since he is the reluctant one, learn to get comfortable with silences and find out if he will fill the silence.
You have to be ready for the idea that it may be impossible to get him to be open with you. Sometimes a therapist can help change this situation where your own efforts have not worked.
