Ex girlfriend with close/bestfriend

[Spitzer]

So lets go back two months and take the story:

2 months ago
- Me and my girlfriend og two years brake up and we both feel its a good thing

1,5 months ago
- I start dating and old flirt
- As revenge for me moving on my eks kisses with my bestfriend/he kisses her i been told none of them held back
- He talks to me about it and i let them both know that i disappointed, but that they are both grown ups so its not my place
- He ask if it will hurt our friendship and im like well not this time

3 days ago
- I get in a big fight with my eks and she tells me that her and my friend is dating and going to become more
- Me and my flirt/fling decided to call it quit
-Apparently my eks and mate have been seeing each other ever since the first time behind my back

So in 2 days me, him and 2 other mates are going out for a dinner and later birthday party at my sister
He still havent told me so here is what i want to do

1. Confront him to day and just skip the dinner and ask him whether or not it's true and then if it is that he must choose to be in my life or my ex gf like because me and her is not going to share a life again...and then ask him to **** out of my life and stay away from my sisters party

2. same ting but wait until after the dinner and the party and pretend everything is ok and just wonder why he havent told me yet when he knows that i know about my eks and him

3. Accept they are together and just smile and wave at parties when they kiss and stuff (yeah right, wont happen)

4. Get Big Al(bro) to beat the shit out of him (yeah right, wont happen, but more likely then previous statement)

So what should i do and what would you guys do if your bestfriend starts dating your ex-gf :s?
I know i didn't tell them strictly that it was off limit but they should know that :s

Be the bigger person and do nothing. If you say anything to him-it will make you look jealous and she will think you still want her. Dont give her the satisfaction. I think they both betrayed you-exes are off limits (not ones that you dated for a month but two years is different)

Maybe if it was a year or two later and you were with someone else and happy and those two got together-it would be okay but within months of a breakup is really not cool.

Just distance yourself from this "friend". You can just nod if you see him and acknowledge his presence. You dont have to be his best mate. Make new friends and get on with your life

In the end that would be the best solution, however i need to confront him and confirm it all so i know that my ex just isn't playing around with my and him. Because i don't want to cut off a friend just because of rumors and what my ex said. Personally I only saw them together that one time, but it's a small city so there is a lot of rumors about other times and dating and stuff like date.
However i prefer to go to the source and let him know that he crossed the line

If that is what you need to do then do it. Just try not to come off as jealous.

Michelle's advice is good, but you seem determined to walk into a buzz saw. We all love a good train wreck..please let us know how it turns out.

If you are that determined to confront him, then be sure to do it as a mature, grown man! Not some jealous little boy, throwing a temper tantrum. Let him know that you know what's going with him and his ex, and that because of this, you can no longer be friends, and leave it at that. The ball will now be in his court. If he decides his friendship is more important then he'll call you. If not, then just distance yourself from the situation and move on.

Just what i did, he said he will come back to me with an answear so now i will wait and see.
The reall train wreck will come if he doesnt dump her because if i distance myself all of our friends will hate him.
