Really starting to feel like i'm talking to myself here. lol

Anyway, wife woke up, acting like everything was fine.

The conversation:

Me: "Just to let you know, I'm going to go ahead and file tomorrow."
Her: "Why? Ya, that's always nice to hear 5 minutes after you wake up"
Me: "You chose not to participate in or work on this marriage. I'm really disappointed in that, but I respect your decision. You're free to do what you want, and that includes sitting at a guys house party (4 young guys, she's only girl) by yourself till 4am. But getting too drunk to be able to drive our son home when he wanted to leave is completely unacceptable".
Her: "The guys at that party are young enough to be my kids. Nothing obviously happened. And I didn't keep our son there, you came to pick him up. I needed to sober up, which is why i was there so late. All we did at that party was play beer pong".
Me: "So in order to sober up, you played beer pong for 4 hours?"
Her: "Fine, make me the villian. I guess I'm a terrible person and terrible parent. Maybe I'm struggling with some issues, ya know?"
Me: "Never said you were terrible, although a lot of other people are. I understand your issues, but that doesn't excuse that kind of behavior. Think about everything that happened yesterday, then ask yourself who the F does something like that?"

Then I walked away. I"m sure I handled it bad, but I don't really care anymore.
