Kristi, I had a chance to go through some of your posts, and it's weird how similar our situations are!
You described H as emotionless and in control - W is the same way. She is being so weird. She met OM about 3 weeks ago, and since dating him, has started down this path of "We haven't been married in a long time" - "our marriage is just a piece of paper" - "you aren't a part of my life". Funny how all the nice stuff I've done for her just sort of disappears when OM pops in to the picture!
Even now W is being weird - she had OM to dinner on a Thursday (I didn't know it), came over to drop off kids on a Friday, and she was friendly and smiling, and whispering to me about presents, laughing, etc. I found out about her having OM over for dinner, and told her I was filing divorce. I guess that might have made her a bit sour too!
So she won't speak to me, leaves very angry - then texts me about having the flu. I asked her if she needed anything - very polite, then didn't text again. Didn't speak to her for 5.5 days.
Anyway, you are probably a TAD better off than me because H brought you a bamboo plant. My W probably would bring me a rat at this point!
I had just told someone that things were about to get UGLY - I have detached, and am NOT taking any crap from W, and she is definitely not liking it.
I have made my goal this: I will not contact W in any way until SHE calls me, and has a pleasant conversation that is not about the kids. It may be about frogs or roller skates, I don't care. Honestly, it may take 3 months for this to happen (or never), but I have set this goal, and I will not budge!
I would suggest you do something similar if you haven't already!
