I've been out on three dates with this guy. The first one he initiated. The second one we bumped into each other at a coffee shop and ended up having dinner (his idea) and the third one I intitiated and he accepted. All of the dates have ended with a hug (no kiss). Do you think it would be appropriate to call him and ask him if he would like to come over for dinner Sunday? He does respond when I call him and acts interested but sometimes I just can't tell. Any advice would be helpful.
