i am looking for a spanish song

Question

i am looking for this spanish song, it is probably impossible to find because i don't know much about it. even if i found the artist i could probably find the song.

it is a slow song sung by a male singer with long curly hair i believe. in the video there is a women in black boots and a skirt walking around town. she has a boyfriend and they are in love then something happens and everything the guy had starts to disappear, the women later on gets off a train and kisses a guy.
