In your OP, you mention lots of qualities he has that you appreciate, and also lots of qualities he has that you used to love and have now outgrown. Are you sure of that? if you met someone who constantly interrupted you and hounded you and belittled you when you felt a bit like retreating inside your shell, perhaps you'd hanker for the days of peace with him.
I'm not ignoring your problem. A silent DP can feel like being stonewalled. Lots of psychological tests show that being ignored is far worse for one's MH even than being attacked. and silence can feel like rejection to an extrovert.
You keep saying you want him to change and there's no one else. This suggests to me that you don't really want to leave him. You want to have a better life with him, not without him. Is this right?
if so, I think you need to try and broaden your range of ways you communicate. Definitely suggest going travelling again, with DC. There are lots of ways of communicating that aren't words. Sharing similar taste in music, comedy, even TV - these all help breed a feeling of being on the same wavelength as your partner.
One thing he needs to address, which is not your problem, is his daughter thinking he has no interest in her. He needs to make an effort, however forced, and stick to it until it becomes natural. And you could help by explaining to DD that there are other ways he shows his love or communicates with her - things he does for her or with her etc. Help her to appreciate him.
You could even try a cheesy old improve your relationship trick like complimenting him on stuff he does that you appreciate, as often as you can, and especially complimenting him on any lovely chats you have, however small. That might help develop a healthier communication between you than you barking and snarling at him. No one responds well to being bullied, and you're getting no joy from being his bully.
