First, I love that song! Next, many of my clients are leaving their spouses for the exact same reason - they have grown apart. Some try counseling and it works for them, some it does not work for.
My thoughts are that first you need to be honest with him and try to get him enrolled in counseling. Maybe you need to go also, and define it as co-parenting counseling so that you can assure it is not marriage counseling and that you are both working on divorcing. Next, I would tell you to ask him what times with your daughters he wants, instead of telling him every other weekend and one day.
I would also tell you to go and see an attorney to help draft the separation agreement. If you are willing to give him the majority of marital assets, I am sure he will agree with you sooner. Best of luck.
