So I took your advice....
Told BIL that I didn't want to talk about his sister anymore. I think he just likes stirring the pot. He did, however, continue to share things, so the SO stepped in and said that it wasn't cool to be broadcasting HIS dirty laundry to me. Nice. MIL (soon to be former) and I had a brief and very charming (no sarcasm at all, seriously) email exchange in which she told me how much she appreciates everything I do for the kids and how she understands that my reluctance to spend a great deal of time with them, has nothing to do with them personally, but just the situation.
Then camp crazy blew up the last two days and all of the discussion about leaving me out of it went by the wayside. First, BM figured out who I am, at least my name, and decided to inundate SO with several emails regarding what a "Looser, slut whore" I am. I am assuming she meant loser and I'm surprised she can't spell it. Then, she sent nude text pictures to some guy who does work for her parents on their properties and his girlfriend, who works with SO, told him all about it and he then forwarded this inforamtion to the IL's due to the fact that he is no longer willing to work for them (the guy who received her bloated alcoholic photos).
Meanwhile, camp crazy explodes on the IL's who then inundate SO with calls and texts about how insane she is. The daily telephone calls we are forced to make go unanswered. Yet she is threatening him with contempt. It's been a crazy five days and that doesn't include the shit at work.
So, now, it's all quiet at the camp, and I am nervous because the crazier she is, the less likely she is to lose her shit on me. If her life is a toilet bowl of swerling feces she will be too distracted to mess with me. Two of the four kids are sick and the other night I got to wear vomit because both kids threw up on me. I can handle vomit, but maybe not in that quantity. We have a trip planned to see my family this weekend and I am worried about the sickies being transfered to my nephews, so it may be just me on the trip but we will have to see.
What the hell happened to my normal and organized life?
