Movie about a female assassin who falls in love

Does someone know the name of this movie? Been looking for it for decades. Must be a American dark comedy from the 2000s. It is a movie about a female assasin who kills men who are having affairs. She has a weakness for chocolate. She get the mission to kill a average (but innocent) man and somehow he wins her heart by giving her chocolate during a picnic/date. In another scene, she strangles him but somehow her heart melted when he showed her the gift he brought during being strangled by her. She kisses him.

Sexy Killer: You’ll Die for Her (2008).

Or on this list?
