Because I am.
I have been with DH 6 years, have DD 2. I love him and care about him, we don't argue, we are best friends, we have the same sense of humour, goals, aspirations hobbies. We are a great couple.
But I am categorically not attracted to him. It's really shit. The thought of losing him and splitting up our family scares the hell out of me. Can people sustain a lustless relationship? Is anyone in this position?
