Trying to find name of film
I saw this movie some time ago already on TV so its probably 10 to 20 years old maybe more. At the start of the movie a woman gets defenestrated from a flat of a tower (not sure about the tower but was sort of high).
A new one comes to move in and she soon meets the owner of the building (or his son, maybe). They do some jogging together, he invites her to dinner and they have an affair together. However, she realises he's a dangerous person.
Unfortunately, I can't remember what follows but if it makes anyone think of a film's name, please enlighten me.
Thanks
