Oh, WAW, I think it would've been OK to call him a donkey for a while now. Your 4 year old isn't liable to remember his little talk, but that's tremendously insensitive to you and to your daughter.
I think your feelings can grow for your H again, but he's going to need to do some growing as well. Sounds like he's still hurt and in his shell and trying to control the situation. I think you've been clear with him regarding your feelings and that you still want the marriage to succeed. What it's going to take for him to believe that message, short of you coming home with your tail between your legs (not a good thing for anyone involved) -- I have no idea.
Stay patient, bring back the boob shirts (for all men, please, bosoms are an absolute good in the world), and focus on making yourself stronger. I just can't see any other strategy for you know.
You're still doing family things together right? Dinner once a week or something? Maybe you could host him at your place and trade off? I don't know. It's like he needs some interaction with you to keep up hope, but you've got to manage that situation without giving him false hope that you're on the verge of everything being OK. Maybe hit him with a real 2x4? jk. sort of.
