Just read up on your sitch. I think you're in a pretty good position actually! Like others said before have patience. And when you think you're out of patience, you're gonna need some more. Time is on your side, but you need to keep up your good changes, your 180's. Consistency is key! You're doing great! Most important thing: don't forget to make yourself happy. All the things you do for him are great, but don't sacrifice yourself.
My W and I are sort of stuck in "friends" mode also. We're the best of friends, she even admits that. I just got a long email from her that confirms that she's noticed I have changed, likes the changes, but somehow her feelings have not changed.
