With regards to the resentment, I hope you are exploring true forgiveness. It's difficult, but this is something you can do on your own and it is so worth it.
On your H's side, I think establishing trust again is going to be key, so I'd explore what he needs for that to increase over time. There's no short-cutting it, but for me, a lot of small, simple things help...communicating the schedule, communicating changes in plans, coming home when she says, etc. You probably should discuss transparency for both of you if you haven't already.
Keep up the good work...it sounds like things are progressing. It's a long road, but at least you are walking it together now. And stay in touch!
