Im not sure how exactly you are acting. But, in my opinion, the impression you want to give is "I will be OK without you".

Just acknowledge them, and accept that they are feelings. And that they are temporary.

See if you can focus on you during IC. What are your goals for the next few months while H is gone? How can you build Lost08 into Lost09, the woman he would be a fool to leave?
