You don't have to tell OO anything, OO knows he has been lying once that call was made to you. Every day that you are there is causing the OO more and more doubt about your H.
Another thing, don't let H give you the excuse that he is doing this or that because it is the best thing for you. Tell H that you are perfectly capable of deciding what is or isn't good for you.
"Our life is what our thoughts make it."
Marcus Aurelius
