Trying to save my M. W not really trying though.

[etrain]

I was actually considering contacting OM's W.

Right now, I'm really wanting to confront her about this....or at least asking if this OM is part of the group going out tonight. If my W is being an evil, manipulative cheater, I think she should be called on it.
Can I really sit back & give her space to screw this OM...then expect her to come crawling back to me & I take her back w/ open arms? I'm being played for a fool here.
