I still love my husband, but I want a divorce

I love my husband very much and don't want to hurt him in any way, but I know I'm not supposed to be with him anymore. I am happier when he's not around. I don't feel the way I used to during sex(when we do have it). His kisses don't leave me numb anymore. He doesn't show or tell me he loves me anymore. It's a very slim chance that we will be able to have kids. I don't feel right being with him anymore. I'll never get to live the way I want with him. I feel so horrible for wanting to leave, but I don't want to feel bad for doing something that's going to be good for me in the end. The last thing I want to do is hurt him, but it hurts me more to stay looking at someone I love so much but can't have what I want with.
