WAW is having affair, anyone with some advice?

[kenva]

The last few weeks I have been going out on the weekends, after our son goes to bed. I would tell W that I am stepping out for a while, coming home around midnight. Since those last couple of weeks, she has become really cold, avoiding me at home, going to her room after dinner, and giving me the death look. She has gone to her family cook out for the 4th, and not including me. We both have birthdays coming up, and have no clue how those will go. Also a bigger cook out with just about all of her family, cousins, uncles, so forth. Seems like I'll be left out of that one too. Just curious how she is going to handle answering where I am that day, since the others don't know we are separated other than her immidiate family. The only time she would say anything to me, is when our son does something wrong, "are you going to fix it?" Sometimes I get to the point where I just want to say, serve me papers, stop the BS, and make it a nasty divorce, because she thinks a divorce will turn out to be fine and dandy.She wants her cake and eat it too. Life isn't fair. When I get like that, I simply walk away, play w our son to get my mind off of it, or smoke a cig. I just don't know how much more I can, or better yet, any human being can take anything like this.
