My friend!
The same thing happened to me and I learned the hard way. It's painful and lots of things are racing around in your head which makes it hard to think logically. I'm sure you've heard this before, I just wish I knew then what I know now because looking back on my state of mind at the time I discovered my long term girlfriend had cheated, I know now I did not make a rational decision.

It was extremely difficult but I forgave my girlfriend and tried to fix the damage to our relationship because I did not want to lose what I THOUGHT I had. I know this now but at the time it was painful and I did not want to lose my girlfriend.

We stayed together for a while but after some time she had another affair and I went through the pain all over again
This forum isn't the place for a deep and meaningful discussion about the merits of my decision to forgive her or my feelings so I'll summarise what I've learnt from the experience.
1.If your partner truly loves you:
a. she would not put herself in a position where she could be tempted to have an affair
b. she would not allow another man to think he had a chance with her
c. she would have rejected the other mans advances towards her
d. she would have told you if the other man persisted in making advances towards her
e. she would have ended the affair after the first time it happened, not continued

2.Respect is a most important characteristic that forms the basis of a strong and meaningful relationship. The fact she had an affair with your best friend is worse than an affair with someone you don't know and is evidence she does NOT respect you.

3.Betrayed by your best friend is one of the worst betrayals you could experience. Your best friend should be looking out for your best interests and not taking advantage of your friendship to get to your girlfriend like a snake.

4.The first time someone decides to have an affair is always the most difficult because they are afraid of getting caught and afraid of what you might do if you discover the affair. If you forgive her and get together again, well it's obvious, she got away with it without consequence. There is nothing to be afraid of anymore and the decision to have an affair the second time will be easier. Do you really want to go through the pain again?

5.Honesty in a relationship is an important value; your girlfriend lied to you during the affair with your best friend about her friendship with him. She failed to tell you about his advances towards her, she failed to tell you about the affair and it appears she continued the affair. This represents many lies.

6.The best predictor of future behaviour is past behaviour. She has lied to you in the past and she has had a sexual relationship with your best friend, these things demonstrate a lack of morals, lack of respect and are a good indication of what a future with her will be like.

7.If you get back together again the relationship can never be pure because in your mind you know what she did and it will haunt you. If it does not work you will have wasted another period of your life (months or years) and for all you know the right girl for you could have walked right past and you lose the opportunity to find happiness because of the time wasted fixing a broken relationship with your girlfriend.

8.When something is broken, no matter what it is, you may glue the pieces together, fill in the cracks and paint over it but in the end the cracks are still underneath and will always be a weak point. Would you pay full price for something broken and repaired? Don’t you deserve better?

9.Like the saying goes, "Hurt me once, shame on you. Hurt me a second time, shame on me!"

I recommend the song "Because" by Jessica Mauboy, I think the words are appropriate and may help sort out your thoughts. Check out the lyrics at http://www.6lyrics.com/music/jessica_mauboy/lyrics/because12.aspx

Good luck and I hope my words are of assistance to you

If she did it while she was your EX - then get over it.
If she was doing it while you were together...then get over it.

You are most likely under 25?
Get used to it...people don't understand what relationships are about until they are much older...if at all.

Work on yourself.

Once you take the gamble to cheat on someone the temptation will always be there especially if you got away with it. As much as it hurts to let someone go the pain and the distrust will ALWAYS be there. Do you always want to be second guessing where they are at, what they are doing or who they are with? I do believe in the saying that it is better to have loved and lost than to never have loved at all. Let her go. A real woman would have talked (no texting, IM, facebook, twitter, etc)to you about how she was feeling before she betrayed you. Breaking up would have been much better before she used your BF as back up who also has no morales. Let her go, its not worth the misery and remember females outnumber males in 7 out the top ten largest cities in the US.

KILL Er

i think you should talk to her.

fuck that bitch up.

Talk to her about what?

She's been _ucking someone else! What do you want her to say? That he wasn't as good as you? Man up and walk away, there are better women out there and without the worry of trying to second guess where she is and who with. The guy deserves better!
