i need to be willing to end it in order to save it.
It's that or just accept her having a boyfriend(s).
It's hard to say without some more details, but it also sounds like you may have rugswept the first affair. Were there any consequences for her the last time? Or did you just forgive and forget and move on shortly after?
As far as snapping her out of it goes, you seem to already realize what you need to do. I played the pick me game for a couple of weeks and all it got me was humiliation. Then I told my wife she was free to pursue the other man, but she'd be doing it as a single woman. I called divorce lawyers and real estate agents right in front of her and started setting up appointments to file for divorce. Once she realized I was serious she broke down and begged me not to go through with it.
That snapped her out of it right quick. She dropped her AP like a hot rock, cut off all communication, transferred her work location, and blocked him on everything. She's been as close to a model wife who desperately wants to save her marriage as one could hope for ever since.
I can't tell you what your wife might do if you do something similar, but your motivation needs to be to get out of infidelity as soon as possible. That was mine, and I was prepared to go through with a divorce if it came down to it. If you do go that route, be prepared to follow through with it. The last thing you want to do is backpedal after saying it, tho you can pause or stop it of she comes around.
Imo, there are worse things than divorce, and sharing my wife with someone else and living in infidelity is one of them. If your wife wants to remain in the marriage then she'll do whatever it takes to make it happen. If not, then do you really want to be with someone who isn't as committed as you are? Spend the rest of your life tolerating her sleeping with other people or acting as the marriage police?
I know this is hard. Infidelity is probably the worst experience I've ever gone through. It's traumatizing. Thats why I had to get out of it. I'm really sorry you've found yourself here. This is a club no one wants to join, but I'm glad you found us. There's a lot of collective wisdom here. Check out some of the articles in the healing library and keep posting here. It helped me a lot just talking about with others who knew what I was going through. I know it doesn't feel like it right now, but things will get better for you, one way or the other.
