Lovers reunited after over a decade of separation

Suggest me a book where two people who were madly in love when they were young lose contact and reunite when they are older. I liked The Lost Wife but I’m not wanting the separation to be due to something tragic (it’s a WWII book and the characters are Jewish. While escaping Prague they get separated and end up believing they are dead and one ends up in a concentration camp..) Bonus if the characters reunite after being married and/or having kids.
