Our sitch is so much the same its scary. I didn't know my W took herself off the ADs and when she did things got crazy. I also encouraged her to stay on them, but only made things with us worse.
My W never left the house. In the beginning she would be out of all hours of the night. Secretive with her phone and text messages. There's pleny more that happened and I DB'd my butt off. I've backslid many times and I still back slide. I would constantly think about my stich which caused me stress leading to medical issues.
Now, she goes out... I don't care. She comes home I greet her with a smile and go out. If my SS is home and willing to watch our D we go out for drinks.
What I should not do. Ask we're we are in our stich. Go on and on about how life would be better if she L me. Not take care of myself and stop staying out at bars b/c there's no where else to go.
I think you've picked a good name which will be with you for a long time. Be true to yourself and don't get involved with drama of his stich.
