Not sure which might you were referring to so I'll answer both. If you mean "we might be able to talk" I mean that I'm not sure there's any room to talk. She stopped caring for me a long time ago and used this OM to satisfy her her emotional (and likely physical) needs. If this M fails this will be dead marriage #4 for her; I now see that this is a recurring pattern for her. When the going gets tough she starts to separate, finds a way to break the relationship (infidelity) and moves on. It's very possible that this ship has sailed already. I also mean that I don't know if I even want to try to work this out. Since pulling my head out of my a$$ I've come to see that I have a lot to offer a partner and my W has failed to honor or appreciate that for some time now. I'm conflicted about the work being worth the hurt nand the very good chance it work work anyway. I also struggle with the "once a cheater always a cheater" possibilities.
If you were questions when I said "it might have worked" I mean that she appears to have canceled the secret accounts and has stated she knows she needs to come clean and be 100 truthful.
