[Acy]

So it's really hard to stay upbeat around waw. She talks to OM for hours each day. She wants to go to my family's functions, like Thanksgiving and Christmas. It could be just for our sons sake. Should I let her go to those functions? Should I go out with her on weekends? Or watch tv with her and my son? All these little things. Should I still be her best friend? I really feel like just cutting off all the seeing her and talking to her as I can. My thinking is she may realize she can't go out to dinner with online boyfriend. And going out to dinner is a big deal to her. I want to just focus on my life and spend as little time with her as possible.
