It is good that you are still going to go. Talking to the C without H around is probably better so you can make sure when H does hear how you are feeling that it is in a constructive way that is not going to push him away. He has definitely made some progress so you don't want to stop that by making him feel worthless again.
Have a good day and hopefully you can think of something fun to do for you!
