Good for you for not biting!!

The anger bit isn't working so now he is trying the pity bit (been there done that).
Don't get sucked in, just say "I understand". He is really telling you how he is feeling, but if you give him too much right now, it will blow up on you.

This is JMO, but your husband and I seem to use a lot of the same tactics ( or at least I did lol) and I am trying to think what I would have done and been thinking.

Don't hate me lol! Working on changing my interaction habits!
