Your H's behaviour is definitely typical. Don't take any of it personally though or you'll end up feeling worse and worse. As AS says, you have to focus on yourself.
Do what you need to do to protect yourself (ie, lawyer) and don't be pressured into having that talk today if you don't feel ready. Agree to set a date and stick to that date. I'd even recommend airing your thoughts about what you want to say on here so that you can get feedback as to whether it's a good idea or not. Once said, words can't be taken back and you don't want to be misinterpreted.
In the meantime, focus on making yourself a better person. Is there something you've always wanted to try but haven't yet, a hobby you used to do but stopped? Keep yourself busy so that you don't have time to dwell on your sitch. Always remember that you can only change yourself, no one else.
Stay strong and remember that you are not alone.
