She IS interested in someone else. You just can't or don't want to admit it. This is what women do when having an affair.. They tell you they "forgot" to tell you about a meeting..
They call you up the DAY that they are going to be around their affair partner and they say things like.."hey, take a day off in August for our kids so that we can spend the day together"..
This is guilt doing these things.. THINK about it.. Suddenly she is asking you to take a day off right out of the blue.. the same day she has another board meeting and of course it is Jim and Joe that are at fault because they "asked" her to go have a beer..
Stop being in denial about what IS going on... It is only hurting you. Setting "boundaries" isn't what this is all about...
There is only ONE boundary here.... And you need to focus on THAT boundary and that boundary alone.. Your wife is going out to bars meeting other men.. 2+2=4... Always has always will. AND you are ALLOWING it. The attitude should be this..
"you can go out and be with anybody you so choose. You are totally free. However, you can NOT have me too. End of story. IF that is what you so choose, then I want you to find another place and move out. The sooner the better.I am not interested in being with a woman that is my wife going out to bars and drinking with other men. I know that seems old fashioned, but my mind is made up. Please find another place to live and I will start divorce proceedings right away"..
