Your WW left on her trip obviously trying to ‘lovebomb’ you back into complacency because she suspected you were catching on after the dance incident.
She goes away with POSOM’s W, and the W of your friend who tipped you off, who seems to have been an A cheerleader for your WW and this shit couple.
IMO that weekend was spent with your WW and her crappy friends discussing how to approach dealing with you.....and they may have been fully aware that you had been tipped to the A by your friend because it is very likely he also told his W about telling you.
They probably knew you planned to meet to be filled in on that Saturday....and POSOM was tasked to stay close to you all night being annoyingly friendly to prevent you talking to your friend......in addition, your friend was probably being bombarded by his W to say nothing to you and ‘stay out of it’.
As a result you never heard from your friend details or proof about the A....something you were told several times you absolutely had to get before your WW returned.
So all you had was what amounts to a vague rumor from your friend to hit her with.....and as further evidence that your WW was made aware during her girl’s weekend that you were tipped off about the A, you only need to observe that she INSTANTLY knew who had told you.....of course she did.....because HIS W told your WW all about it during the weekend.
So your WW.....knowing you have nothing but a rumor, and have not followed up with your friend to get evidence.....has now dropped the ‘love bombing’ approach and gotten angry and confrontational.
And it has worked.....you have essentially backed down on everything.
This is exactly why some of us advised you that you HAD to get in contact with your friend ASAP and get all the info he knew.
I am sure right now that he is being pressured by his own W and the other couple to keep his mouth shut and say nothing to you if you do reach out again.
That said.....trying to get in contact with him again on the hope that he STILL thinks you need to know what is going on, regardless of any pressure that might be being put on him, is about the ONLY chance you have left to find out the extent of this shit show.....
And only when you know that will you know if it is even worth trying R with your WW....or even worth it to stay 5 years til your kids are out.
And btw.....the reason your WW ‘offered’ up staying for their 5 years is so HER lifestyle isn’t disrupted.
She gets 5 more years of you footing the bill for her while she has time to get her ducks in a row to take you to the cleaners in a D after the last kid leaves.
Do not for a second believe that your WW’s offer of 5 years is for your benefit or out of love for you.....
She just wants to use you to keep her standard of living until she is ready to leave.
Good news is.....though she clearly took Round 1 of this bout from you, it isn’t over.
Pick yourself up.....talk to your friend and get that proof....and then expose the A and file for D.
Rock your WW’s world and plans.....show her that she will not get one day more of her cushy life on your dime.
Start fighting!!!
