Sister stole my guy...

So I really liked this guy who was 17 and im 15 and my sister is 17 and a lot lot lot prettyer then me!!! like a LOT!! and well e verything was going great with him until he saw my sister and now the like make out on my couch and it makes me literally...

want to kill her!!! what should I dooo

you should tell your sister that you saw what she did and ask her why she did it. also, I may consider that you break up with your boyfriend. he shouldn't be making out with your relatives.

I've been there babe, I know how you feel, but nothing lasts forever, but hate, so just let it slipp I know its hard but find a guy thats into you he seems like a jerk to go for your supericial sister. (: stay strong hun and be the bigger one (:

it's obvious who he is interested in more, hunn. you can't point the hate all at u.r sister, even though she's wrong as hell..you gotta remember he's wrong, too. so juss say screw the both of em and be done about it. you'll always have love for your sister but forget about him and find someone else who wants YOU, not u.r sister. also : despite what you think about u.r sister as compared to urself, who have some, maybe a lot of GREAT qualities that she lacks, and u.r future guy will appreciate em !! how do I know ?? because I'M that big sister you have..AND MY OWN YOUNGER SISTER thinks I'm overall BETTER than her;;because I'm smaller and she always says how much more pretty I am than her. but I know she has a lot of good qualities that I DON'T have;;she can cook, she's GREAT with kids/babies, she has the most generous heart, and she does nail designs out of this WORLD !! a guy is gonna appreciate those qualities in her that a guy couldn't find in me. that's how you know I'm not sayin this juss to be nice, I'm tellin the truth !!
