Help me find a movie based on the plot

the film is not old, about 19-20 years old (approximately), a woman is married, she begins to correspond by mail with a man (?) (maybe a guy), they corresponded for a long time and in the end they seemed to fall in love, the husband never seemed to find out, and then she I met this guy by correspondence, but it doesn’t seem like there’s a happy ending
