I´m looking for the title of a movie where there is a woman (blonde) who works with selling art at a little shop. A scene I remember is a male customer who is rude and then another man comes in.

The womans son dates the mans daughter. Then the woman and man starts seeing each other. The man and daughter had a mysterious past, they moved a lot, there was something about women. The daughter said something like, you promised you wouldn’t do it anymore… to her dad.

Another scene is when all four of them is at the womans house and the man said he needed to go to the bathroom but instead goes in to another room with a computer in it.
