She sounds like an asshole. I'm sorry it happened, but you're better off without somebody like that. Maybe she isn't over you, but if that's the case, it's a rude and immature way of dealing with it. You can do better.

That's a bitch move and incredibly immature. I'm guessing she was embarrassed over being dumped and caught cheating that she pulled this stunt just to get a rise out of you! It's probably best you broke it off now rather then later!

Wow, what a bitch! Consider yourself lucky that she's out of your life!

Google images a picture of an STD and email it back with the caption, "what I'm glad I don't have."

I don't understand why you are upset you obviously made the right decision to leave her... She is now someone else's headache be happy and find a nice girl :)

Stupid bitch is going to try to get back with u when the other guy gets tired of her shit & dumps her...when this happens, punt her in her uterus

The ex is definitely hoping for a reaction from OP. Best action is no action at all. By not doing anything, she won't get the reaction and attention that she wanted.

Oh wow, she's bloody charming isn't she? Like you need an arrogant bitch like her, man, you could do so much better :) Forget her, she's immature and attention starved.

what a ***** bag!!

that was immature of her now u really should b over her
