I have reread the post chatterbug and I'm prepared to deal with it. Actually, its quiet without her at home and I don't have to think about what she may say to me. If her plan is to go out with the OM more to make me upset, I don't see how that changes what she has already been doing. So far, not a great plan. Being alone [censored], but I'm starting to get used to it. This will make it easier to start NC with her and to continue to GAL. I'm still too attached to her.
I did talk to her on the phone, but I followed the rules on keeping it to kids and finances. It felt good to be just business with her and I could tell she was confused when she tried to start a friendly talk on the weather and I nicely said "I'm not sure what the weather is now. Anything else I can help you with? No, okay then good bye."
Over time you feel better and better for being "alone". You won't feel lonely. You will feel good. It's also going to be harder for you after this stage to be close to anyone else who doesn't really want to be close with you. It's going to feel uncomfortable. It's for your own good.
Maybe the entire time there were signs you just weren't seeing. You will come out of this with better relationships. Either with your wife or someone else.
