I’m not entirely sure that the part of the movie I just described was the whole plot but that is the part I remember. Her kids (grandkids?) take her to the other country (possibly Italy) and they try to find her old love. At one point she finds who she thinks is him but It is a young man. The kids think she’s crazy until they realize that is his son (grandson?) Thank you so much guys!
? “Letters to Juliet”(2010)
