Having been married 4 times longer than you and H have been together, I can say that you don't always feel "in love". That's a myth. Yes you still love them and you have a commitment to them and the children and you just keep working on things, knowing as SD said, feelings will evolve and change.
The key is to keep working on you, doing things that make you happy, having your own life away from H and the kids and when there isn't so much pressure on being "in love" you might find that you are again.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
