Ame, if H brings up anything R oriented, just listen and validate for now. Your goal here is to create a positive, wonderful time in your contact together, that's it. Don't think about how it is that H will be going home to OW, instead, think of how it is that you and H are having a great time together, whereas others don't even get that opportunity. If H's going home to someone else, it only means he's not ready yet to return, that's all. And all that means is that more time and patience is needed, time for H to become convinced as to where things would be better for him; time for you to build more positive experiences with H, time for H to see the changes to allay his concerns that things may not be different. You just feed him those positives, be bright and happy and cheerful, which are attractive qualities, and let time handle the rest.
