I'll preface by saying I don't know the full story, but this sounds like a typical High School story. I.e. "I think she finds me attractive, but I don't know, so I'm just going to wait it out". Think about it, You're talking about lovenotes and YouTube hits.

 Look, after a certain age it's not worth dealing with "gray". It's black or white, No games. "Is she attracted enough to be with me?"

They say there are two things that make smart men go dumb-Sports and beautiful women. We get highly emotional about both. We loose perspective. 

You gave yourself 14 days. Stick to that. Tell her how you feel after that. Don't over think the room. 

But from my perspective, shes right where she wants to be. And if you're content with that, I say, go for it. Make it purely physical and enjoy.

That's pretty much exactly what everyone else is saying, and it isn't limited to women.

Yup. 
@Runner2016 don't allow yourself to be guilted into a separation. Just because she did not live it up in her 20s does not mean she can destroy a marriage and negatively affect your kids lives. 

No one forced her to get married.  How about some accountability and responsibility. 

And agree with @Angeline, you stand your ground and odds are she'll come around. My ExW asked for a legal separation. Gave it to her. Moved 3k miles away. 6 months later she's on the phone "So when are you coming back? I miss you"

I was to deep into the red pill to even give her a 5th chance. 

Anytime you hear "Unmm" after the "When did you shower last?" question, that's a problem. The answer should always be either "Today" or "About to hop in right now, join me". 

Your hubby just doesn't get it.
Well groomed, and a great scent goes a long way for a guy. Add fit fitting clothes, and you got yourself a man who will be respected.

Your posts are long so I might've missed it, but is Chris Married?
