He does need to earn your trust back after the EA, but trust also has to be granted. Maybe remorse from a proud man might be an expectation too far? Could he act remorseful without actually saying it? And hasn't he already said sorry a few times and therefore actually proved he is capable of using those words?
You're doing really well, be patient and wait for this work thing to finish I reckon (says me pushing stuff at the worst possible time for dh...) He is showing plenty of positive signs, what I wouldn't give for my dh to take D off the table and talk about working on things. Sigh. Your H certainly is not just talking but acting so far, I suppose you need to work out how long he will have to do 180s to prove his changes are real.
