If my heart has moved on, what comes next?

He now is in the place where I was a few years ago. I wanted to go out and spend time with him and plan for our future together, and he was not too serious about all that. I stayed and waited it out. A few months ago, I joined a website to make more friends and find cool things to do (Meet Up) and told him about it. He made no efforts to try to spend more time with me, even though that's what I've always wanted and what I've always told him. At some point in the last few months, I had this out of body experience. I realized that I am not in love with him anymore. He bad talks things that are important to me and for years, purposely did things to annoy me. But I always stuck by! Now I'm like "why the hell did I stay this long?" Now he is trying to change all those things, but I feel like it's too late. My heart has moved on. I've grown and realized that I don't want a man in my life right now that I have to cook and clean for everyday (which is what I do now). I don't want a man in my life at all. I want to move out but I don't know how to tell him. We're married. What do you suggest?
