GF, I'm sorry, I dont' have much time to add anything, what's been said already, is well off enough, go back, and re-read. While doing so, analyze the person you've been through all this, and how many time something similar has happened!
You need change within yourself. I don't think you're happy with yourself as a person and facilitating it on your H.
And above you said, you only want to save your marriage for your the sake of your daughter? Wrong way to go.
Back to the drawing board, and review why your here.
None of what I say here is to be mean. GF if there is a sliver of hope, you need to make some personal observations. At the same time, you need to ask yourself hard core why you want to save this marriage.
