Most Helpful Girl
He is no bro in my Book of Etiquette here, dear, and a backstabber to boot. Not only is She a cheat but now you have found Out-----My brother stole my girlfriend.
Family is family and blood should have been thicker than this water lily. However, he didn't give a rat''s behind that she was yours and just went ahead and took her away.
On the other underhanded hand, she really wasn't yours to begin with if she dropped you and went to his waiting arms... and your bro was never a brother nor a friend till the end.
Forget her now, you see what this little chickadee is all about. As far as your sibling, quit sniveling, consider him a loser and someone whom you know now... you can never trust with anything nor anyone.
Good luck. xx1
