I hear your cynicism. I know you've been living with his indecision for a long time. Given that, how could you not be cynical! Your patience is about run out!
On the plus side, he does seem to be making some attempt to improve things. Do you think he would really be doing them just as a cover up only? Maybe he’s doing it to make himself feel better, but what if he’s doing it to really try to work at things? Would he do those things (call very day, leave the card, do the right things at home) if he wasn't really trying? I know my H would not. He is not that type of person. If he truly wanted to do them, he would, if he didn’t … no way. What about yours?
That’s interesting about the depression. Sounds like he would benefit from seeing your IC if she is trained in male depression. I find it interesting that ‘acting out’ is a sign. Fits mine to a T. I’ve wondered how much depression contributed to his A.
Hopefully your H's time away is helping him put perspective on things. I like the fact that he is calling you everyday! That’s good, too!! Does he know that you appreciate what he's trying to do (assuming that you do appreciate it). I know my H has simple emotional needs like that -- a simple "thanks for doing that" goes a long way with him. Something that I didn't do much before now. I never realized how important it was to him.
