Glad to hear she is open to counseling! That means there is still hope!
This might be obvious, but it is time to start "husbanding" your marriage as you would your garden. Make a point of regularly spending time with her a few hours a night hanging out watching her shows with her, as well as trying to reconnect by finding your common interests and investing some time in them regularly: going for a walk, making a point of going out to eat together once or twice a month as a couple (leave the kids home if you have any), going yard sale-ing... what ever those activities are, make a point of doing them together on a regular basis!
Also, I don't know how house hold labor breaks down in your house, but make sure to pitch in with the dishes, laundry and cooking, etc...
Don't make a big deal of it, don't expect it to change things immediately, don't expect recognition for it. Just do it causally, and regularly. Make a habit of it.
And if there are any little things she likes (mine likes nut buster paraits, for instance) just grab one at random every once and awhile and bring it home for her.
It will take some effort, but if you love her and want to restore your relationship, you need to invest in it.
I'm not saying do these things all at once all the time, but start making a point of working them into your routine.
Best of luck, I hope you can work it out.
Edit: I read this and it looks like I'm suggesting giving up all your free time and everything you might like and bending over backwards for her. I'm not, but it sounds like you need to give up some of it and spend more of it on the marriage.
just my 2 cents
