Suddenly he realizes how much he has failed me

For years and years I took care.. of my husband, my kids. My husband always lost himself in work and sports and I always accepted that. Now I notice I am completely finished and I don't feel any love towards him anymore.

The point is, that because of that confession, he turned 180 degrees. Suddenly he wants to do everything for me and he realizes how much he failed me. I can almost not believe it.

I would like to believe it, but at this moment I can only feel anger towards him. How do we get out of this?
