What is the other movie from this era ? ? ?

There is another movie from around this time (the 80's) that I can't seem to remember but fits in this category. A woman marries a man who is not what he seems. I think they may move to Florida or something. He takes pictures of here. She goes swimming in a lake and there is an alligator in it. Instead of showing concern and helping he laughs and takes pictures. In there new house she is putting up wallpaper or something and a large spider like a tarantula in crawling by her and again he just takes pictures. He sits in the attic and looks at the photos. She leaves and makes threats, something about firecrackers in here eyes. Years later he is stalking her and is caught with the exact things in his suitcast he said he would torture her with. What is this movie. It was make for tv. Maybe even a true story. Help?
