Yep, I agree with OF wholeheartedly. I still think your W is much like mine and I'd have to say at the almost one year mark of separation I've given up completely. I'm still trying to get the money together to file though.
My W displays the same niceties towards me. The other night she wanted me to help her order a computer while I was at her house dropping off the kids. She made sure to sit right next to me on the couch and press her body firmly against mine while I was ordering the computer on the laptop.
Of course, I know she still has OM. She refers to him as her boyfriend to certain people. She refers to me as her ex-husband to those same people even though we're still married. She doesn't seem to realize that things do get back to me.
I wonder what OM would think about her sitting next to me on the couch like that. The latest rumor is that she has cheated on him, with a married man no less. I'm not sure I believe that rumor. But, she does put herself in situations where people wonder and it really wouldn't surprise me anymore to find out she had.
Sorry, I digressed a little there. My point is that moving on is probably a good idea in both our situations.
