Well there could be a lot of things going on. Obviously he has lots of guilt over this. Remeber that after the A it take a while to heal and for things to start to come back to normal. I know its hard to be patient. I think it will become easier for you H to talk to you if you are completely open to what he has to say. Not judging not defending yourself Just validating his feelings. If he feels that there is no reason for him to be scared to talk to you I really think he will open up much more.
I know In my sitch if I felt like my W was a completely safe person to talk to I would talk to her more about my feelings. Right now Im still in the mode of acting as if. Which I dont need as much as I did before but still need it sometimes.
Reaally get to thinking on what you can do to make him feel totally safe talking to you about anything.
