Only thing is from my POV the home is both of yours so how can the router only be yours, it does seem a bit petty to stop her from using it although I do see your point about enabling her to continue using it to promote her ongoing affair.
Definitly stand your ground, you dont deserve a W whose not there for you, you sound a good man keep reminding yourself you deserve more.
I agree with what your say, but I agree with the view (Puppy's threads) that you should not pay for anything related to affair so router if she's using the internet to contact him, don't pay for the cell phone if she's used that to contact OM, don't pay for travel for her to visit OM, etc.
