So I remember seeing a movie about a guy who got married very fast and moved into a house with his new wife and then strange things started happening. The cat drowned in the bathtub. There was hair in the wife's hairbrush that wasn't hers and it turned out the guy had an ex- wife who died, then the current wife found the ex-wife's diary and there were new entries every day.
Not sure about the country but I believe the language was English. The movie was made for TV. It looked like it was released sometime in the 90's. I saw it on TV in 2007, so it can't be anything released after that year. It's definitely not The Grudge, What Lies Beneath or Shutter both the re-make and the original Asian version.
I don't remember much, but I'd appreciate if you could help.
