Send him a text messsage. That is the way he deserves to be dumped.How to break up with your boyfriend when you know he's cheating?
ask your friend what the girls name is. then, tell your bf that she called, ask who she is. if he denies it then say you know.
tell him you are seeing someone else and moving out of town...then, when he calls and leaves sobbing messages on your phone, ignore them and know that he is feeling the hurt as much as he made you feel.

if he didn't care a little, he would have broken up with you instead of keeping you there for when he is done with her. he has feelings for you, he is just stupid right now.

there is no true happiness in this relationship you are waiting for with him.

time for you to thank him for not getting deeper in love with him in this deceitful relationship.
Firstly, your BF's ';bff'; might be lying for a shot at your unmentionables, OR he might be lying because he doesn't think you're a good match for his friend and is doing him a favor by chasing you off.



Now that that's out... find out for sure if what you think is happening actually is. Then, if it is, you should take a picture of yourself cheating with some other guy (don't include his face or any other identifying features.) Print that out, then write on it ';One good turn deserves another. Consider yourself dumped, sleazeball.'; Put that in an envelope, and send it to him, attached to a bouquet.
Be clever and catch him in the act.
Call him a lying, cheating b*astard, slap him round the face, tell him its over and storm out.
