Give it time!!!!

act like you dont need him back off and give him a week or two i know its hard ive been going through the same thing for three years with the same guy and now its a for real break up but when you act like your ok and you dont need him and he sees you with your new man hell want you back cuz guys always want what they cant have and when he comes crawling back your in control and remember what he did to you before you take him back!!!! Be strong and back off its for the best i promise
