Is revenge justified or is it just being vindictive?

I just broke up with my partner cause he was two timing me with another girl. I found out about her but she dosent know about me. Should I let her know? I have voice messages and video's to prove my point to her but should I? Am I just being mean and vindictive?
What would you do?

just forget him and move on or even better move in with me!

lol. Thanks lexxel. If only you lived in Queensland. lol

you could move to adelaide!

i guess its best to let things lie, but maybe she does deserve to know that he was cheating on her though yaknow.

Tell her!! If she doesn't know then it isn't her fault and he could well end up doing it too her! Its not vindictive at all!

@lexxel -but I like queensland..lol

but how do you tell a complete stranger that their boyfriend was your boyfriend too? Kinda hard thing to tell someone...

I would drop it as you will only suffer pain from it, meaning the messenger gets shot - isnt worth the hassle - she will soon realise the truth anyway

and about queensland yeah ok!

hmm, put a letter through her door and then walk away forever, hurray.

Revenge is always justified. That's why it's revenge not some random act of cruelty.
Also, the correct way of telling her is to hire a skywriter or buy some air time on t.v to tell her.

i would tell her,to save her the pain of what you are feeling now,when he does it to her,maybe im cynical,but i dont think men like that ever change,think yourself lucky you found out now,isstead of years down the line,when you would have wasted a lot of years on him

I'd let it lie, just concentrate on yourself at the moment.

It'l just stay on your mind longer if you tell her.

Revenge is justified!Tell her that way yuo get back.It's not fair that he cheeted on you.It's wrong.Have you ever cheeted? I cheeted once and that was for revenge.My x cheeted on me with two girls in one night. I got back at him.I slept with his hot,older brother.Then i broke up with him and started to date his brother.whatever makes you feel better. I did what i had to do to feel better and look now after 4 years i'm still with his brother.

Have you noticed throughout this thread that all of the females are saying tell the chick? Well I'm going to do the opposite- What's the point in telling her? Do you know her? Are you friends with her?
If the answer is no, then you having nothing invested in here; therefore there is no reason in getting involved with her. She'll find out when the time is right and that's not for you to decide. But more than that, it's not going to make you feel any better by telling her. Yea, the guy might be at a loss (having lost you and the other chick) but it's not like he obviously isn't sly enough to find two more women.
