Guy makes gift for unrequited love, throws it away

Trying to think of a movie or tv series where a guy spends all night making a gift for someone he likes or gets her flowers and then sees her with another man and throws it in the trash or breaks the gift after losing hope. Something along those lines.

Some ideas were Walter Mitty or The Office and Andy throws a gift away but I can't remember. List any movies with similar scenes if you can. Thanks
