I'm sorry you're going through this again. Serial infidelity is really just about as bad as it gets -- much different dynamic than a one-time either ONS or EA/PA. The recidivism rate for these things is WAY north of 90%.
I'm as pro-marriage as anyone on this site, and worked thru my own infidelity sith (my wife, 5 years ago), and we reconciled. But if she had done it even ONCE again?? I'd be done -- no questions asked.
Personally, I think you should kick her to the curb. She obviously has issues, and you deserve much better than this. Seems to me that Puppy guy was pretty spot-on two years ago.
