Take is easy on trying to read into every single thing your H is doing. I think you might be making some assumptions that may be far off the mark. Are you currently in IC? If not I think you should seriously think about setting that up so that you have someone you can talk to about your current situation.
How do you know he only registered it in his name and that it is under your address? Did he tell you, did documentation come to the house, ect???
