A Lie...Can Cause the End

Girl:Can I ask you something?
boy:Anything
girl:Will you answer honestly?
boy:Of course I will!
girl:No lies?
boy:What's so important?
girl:Do you love me?
boy:...I'm sorry...
girl:That's all I needed...
NEXT DAY
boy (to friend):Have you seen her?
friend:No.
NEXT WEEK:
boy:I can't find her anywhere!
friend:Sorry dude, I haven't seen her.
A MONTH LATER
boy (to girls parents):Is she there?
parents(crying):She's dead.She killed herself a month ago.
AT HER GRAVE
boy:I'm sorry...I lied...I love you...

this isn't a poem, but it was too long to be a quote.
