Thanks to you both. I'm on my way to Barnes and Noble this afternoon to pick a copy of the book up. I should have done so months ago, but I let myself settle into a routine of being her friend and not worrying about where our marriage was going. I do really have to keep my feelings in check and I feel that will be the hardest part of this. At least she tells me she loves me and doesn't feel incomfortable having me do the same. In fact we are taking the kids to a movie together tonight.
I think you're right about dating. That's what we needed from the start. When we came together as a couple I had 2 children and she had one. We never really made the opportunity to date each other. It was just instant family. Now is my chance to really get to know her as I should have done 7 years ago.
