WAW close to moving out, please help

[labug]

She has "taken blame" but I know she feels this is wrong with me:This is about you, not her. What is in your sandbox? How do you know she feels that way?

Did not pull my weight with kids.
Corrected, fully involved for last couple months, probably do over 50% now. She is mad that am doing it now and not before. and she probably will be until she believes the changes are real and lasting, not just a tactic. Specifically I did not pull weight at bedtime and taking kids away on weekends.

Did not schedule date nights, arrange babysitting
She is right, but she didn't seem to want to go. Unfixable b/c I have tried and she wants nothing to do with me now.Defensive

Was moody/defensive at times.
I've gotten over it and corrected this. I'm not sure why I was like this, prob b/c I was not getting what I needed from relationship. Defensive. Was she getting what she needed from the R? I apologized. Good, but actions speak louder than words.

Stayed on computer to much.
I stopped using computer at home a couple months ago.Good, keep it up!

She had commented I was getting a belly.
I was around 172-175 at 22 and worked myself up to ~182 lbs. Back down to ~165-168 lbs now... my 16-18yr old weight. I'm 6ft so that is pretty thin. Been lifting weights for a couple months now.Again, good.

I expect to much sexually. She has talked to other friends and they have sex every 3 weeks or so, so I should be very happy with every week or two.
Not sure what to say on this one, LOL

I know that is been brought up multiple times that it really stresses her out that she is not the wife I need or deserve. I didn't do anything to help this in the past. In the last week I've tryed to let her know she is what I need. I'm not sure how to address this, open to opinions on this one!

Again, you can't change damage done over years in a few weeks or months. These changes have to be because you want to be a better person, a better husband a better father, not just a tactic to get her back.
