I quick note. Sounds to me as if your H is anything but convinced that life with OW is great and going to last for ever. He has big doubts about everything, so that's good!
Don't worry about talking to him of your POV. He may go home and compare notes, seeing how you are willing to go the distance, while OW has already made it clear she won't hang around for him.
Hang in there and keep DBing!
