Hey buddy. IMO you are coming across as angry in the way you converse with your w.
Don't let the pendulum swing too far in the other direction. You can definitely establish boundaries. But establish them in a way that doesn't come across as angry.
Remember... your goal is to become the type of spouse only a fool would leave. If she thinks you are out messing with other women, does that make you the type only a fool would leave?
It's awesome to create some mystery to keep her guessing. But if you make it seem like you are with other women, you might just be giving her another reason to believe the marriage is broken.
I would tell you are out with friends and just spending time with some neglected relationships.
