Should I?

I'm starting to wonder if I'll have ever closure over the one night stand. I'm still angry. I'm still hurt. But it's not big enough to break my marriage anymore. Weird. It's not big enough to break my marriage, just big enough to break me. I'm tired of her constantly being on my mind. I watch her facebook page, but I don't know what I'm watching for. I have only one idea as to what could give me closure. Dayton can't answer my questions because he doesn't remember much from that night. I need answers. Should I contact her? I don't want to speak to her, but I thought maybe I should send her a message on facebook. It seems like the only logical thing to do in my mind, but I'm also terrified that it will open a can of worms. I'm scared it will cause her to contact him. I'm scared her contacting him will cause them to start communicating again. He told her he couldn't talk to her anymore when we got back together, but I have such a hard time seeing him being firm with someone over something like that. He's not the type to hurt feelings or be confrontational. I'm scared he'll be uber pissed, though he doesn't really have the right to be mad. I'm scared she'll be hateful and make the cut even deeper. I'm scared of the details she might tell me. I'm scared I'll look pathetic. I'm just scared to do it. Hell, she may not even reply, and that would probably make me obsess even more. It's an impossible situation. But I don't know how else to get closure. This one night, probably just a matter of a few hours--is ruining my life. It's completely consuming me. It's on my mind, or I'm on her facebook page, I'm questioning him about it, or crying about it...it's got to stop. I've got to do SOMETHING to make it go away. Is this a way to be proactive about it? Should I contact her? Ugh. I hate hoe bags.
