Hmm - my W did the same thing as your H. Back in Feb when I told her I felt like I was losing my best friend she lost it. She even moved back in for 2 weeks, but wouldn't give up OM, wouldn't put energy into M, wouldn't tell me what kind of R she wanted. Big surprise - that failed.
I'm pretty eclectic in my movie tastes - would love to have a movie club! Also meant to mention - you said you liked British movies so I have to bring up two of my all time favs - "Cold Comfort Farm" and "The Madness of King George". If you can't find, let me know.
