Hi Barbara,
He may have been insinuating that he has game.
A guy who has game is normally a guy who is very good at talking to women and getting them to want to be with him.
You have both already been dating for a year. In many relationships, things become a little monotonous by this point and both partners have already started taking each other for granted.
However, you sent him a message letting him know that you wished he was there with you.
In his mind, to still have you be this into him after a year of being together, when many couples would have settled into monotony, makes him believe that he’s got game.
