Hi Wen,
I came here looking for help dealing with my husbands depression/anxiety and your post could have been written about me. I'm reading up and stuff but he keeps worrying that I don't love him which I do. I'll admit that I'm a bit overwhelmed and pull away abit just to deal, but i think he doesn't understand and feels hurt, which makes me feel bad.....vicous cycle, you get it.
I'll bet you husbandis just dealing in his own way, especially since he seems to be there for you for the important stuff. Men like that...it's something they can DO.
But don't expect him to read any literature. Ask yourself, when was the last time you saw him read the instructions manual to anything? Give him some time.
