Fallin out of love....

I really think I'm falling out of love with my child's father...I just don't feel it anymore. It's gotten to the point where I'm no longer anxious to come home after work to see him, only to see our daughter. I no longer want sex from him, I can't look at him, I no longer talk about the future with him, Im no longer anxious for the future of us. It's just terrible. We have very few common interests and we're practically built like fire and water...it's sad. We have such a thick negative past, it effects my feelings now, not to mention a few things of the past represented itself to the present. I want to be a submissive woman, but I can't submit to him. I just can't. I find it hard to respect him due to most of this relationship he didn't respect me. He does now but sometimes he disrespects me in ways he doesn't even know is disrespectful. I'm not a perfect person, no one is, but I'm just finding it harder and harder to be with him day after day. Not sure if I should just drop it, or try to make it work. But from my end, this relationship is dead....
