Go get the book titled Couple Fits. You have an avoidant for an h...as the book will tell you. You can get some helpful pointers on how to deal with his behavior.
know what you struggle with...I did the same with my h for 7 years to no avail (not to say that you may not have better results) before I had enough and moved out...then filed for d. He remains the same so losing us did nothing to fire him up to get off the couch and away from the TV!!! I'm sorry you are struggling this same way. But maybe reading the book will help you. I read it too late to do us any good.
