Your use of the phrase "boogeyman called divorce" suggests to me that you aren't looking deeply enough at the implications and impacts of real divorce on real people. This is not about superficial rubbish like people's opinions of you or the child worrying about how to explain it to her little friends. There is no longer a stigma to divorce except in little pockets of America who will never see any good reason to divorce, not even abuse or violence or addiction.
This is about real change to your kid's everyday life, and a lot of it won't be pleasant, especially if her mother reacts with venom and vengeance, as often happens. Yes, you have to make a decision and stick with it, and other people will also be forever changed because of it, so again, you'd better make damn sure this isn't about some chick or some notion that the grass is greener on another meadow.
Let's not forget the impact on the OP, too. This is a life-changing event. House, family, 401k, bank accounts, etc. Everything as you know it will change.
I don't get the whole 'I am just not in love with her' anymore thing. You did at one point. Look back, find out why, and where you started moving apart. Start again from that point. I don't see anything 'Toxic' yet. Your feelings have changed, no notes of abuse (verbal or physical). Your musings point to someone who doesn't really understand the boogeyman called divorce, because as Trevor points out, there is no stigma attached to it anymore. Popular culture has seen to it.
What better thing to teach our kids then how to overcome the short-term looking for gratification, and actually solving the problem, showing the kids that it takes effort and work, but in the end it is best.
