Is this the end of my marriage?

[P17]

I would simply remind her that your room is off-limits, and that you expect her to respect your privacy.

I'll do that when she is next here. I was going to speak to her about it on the phone but I just thought it would be better coming from me in person.

Then, when she's not home, YOU go thru your office (and your car would be wise as well), and -- much as you would "child-proof" a home when a toddler arrives -- "WW-proof" it. Make sure there's nothing you wouldn't want her to find.

There are a few things she could be snooping for - financial information in here about my business. That would be pointless as if she wants to go for that in the D, I would have to provide evidence anyway. My business accounts are public record so I have nothing, and cannot have anything, to hide there.

Snooping for evidence of another woman. In the drawer by my bed I actually have condoms that I recently bought. This was for no other purpose than trying to be cautious and safe. I had no real intention of using them but I just didn't want to be caught in a stupid situation and make it worse. We all drink. We all make mistakes. We all do things we shouldn't. I just wanted to be safe.

Over the last few times she's been here I have been doing roughly what you suggested - make her a little jealous / suspicious. I asked a friend to call me last night and answered the phone 'Hi sweetheart' as I walked out the door (so as not to make it too obvious). Sending texts while she is here and laughing at them. My D telling her we were going out with one of daddy's 'friend and HER D' etc. My W said last night about her home number being in my D's new phone and I told her I wouldn't need it. So I've been playing detached / hard to get a little IYSWIM. I have been faking it ... but it's better than nothing.

Maybe it's having an effect. You can't get jealous about somebody you have no interest in.

The only other possible explanation is her looking for the letters my D wrote her about how much she misses her. I believe she is going to go to Social Services and try and get contact without myself or D's mum being involved. She may have been wanting copies. Earlier that night she took a photo of something my D drew for her that I never even thought twice about but now it makes sense. I also showed her another letter my D wrote to her telling her how upset she has been and my W went to take it away, I took it back, told her I'd give her a copy and then she asked 'when' ... I got the impression there was a deadline she needed it by.

It's just all very strange. I'd love to know what is going through her mind.

However as you said, I need to WW proof my house as she is up to SOMETHING.
