Yes, they were going to air them all through December, but after a 5 week hiatus, they aired one episode on December 1st then pulled the series off the air again. IMDb is showing the airdates that ABC had announced before pulling the show off the air after airing the 6th episode on Dec 1st.
No one knows if they are going to air them or not. They could air them during the summer, but I wouldn't count on it. They did the same with Eastwick last season, which coincidentally had the same time slot as The Whole Truth. They pulled it off the air, put it back on the air to burn off the episodes, then immediately pulled it again and never aired the remaining episodes, not even over the summer.
