One date in a couple months really isn't enough time to determine the path of this relationship.
Maybe he feels equally cautious as you do regarding this, and maintaining this secrecy of his is his way of dealing with it at this point in time.

Try not to jump the gun on conclusions regarding the meaning of his methods of handling this at this time.
Patience is the key. Faith is the focus.

I wish you the best.
