Well, I doubt it's anything game changing but, I really put my foot down tonight. I told her that I know things aren't easy with our situation because of our one car situation, but while we're in the same house together, there are going to be some ground rules. I told her that while she is in this house, she will not be talking, chatting, webcamming, anything with this OM, or any other guy. That I'm tired of her taking advantage of my good nature and getting everything her way. I'm not going to let her spend as much private time talking to him as she wants, then feel that she can just come to bed with me and cuddle like it's no big deal. I said that I'm just not going to be taken advantage of anymore and if she can't do that, then I deserve better than her and I'll make sure I find it. So, from now on, I'm not doing anything for her other than being the one that drives to and from work. If she wants something, she can get it herself, no more "since you're out" or anything like that.
So, then I left, mostly just to cool down since that was big for me. After about 10 minutes, i get a text from her, "so when are you coming home?" I didn't reply, then the next message from her, "what made you be an ass all of a sudden?" So, I figured that I had to respond to that and simply said, "I'm not going to apologize for anything that I asked for or said. I in no way was trying to be an ass." and that's it.
