I think Sara was suggesting dating as a way to get your husband jealous and maybe to get him to feel what's it like to lose you.
In my opinion, getting him back because he's in a jealous rage doesn't mean he's changed sufficiently to rebuild the relationship.
I think you shouldn't date at all until you are divorced. You'll be able to tell your daughter and show her, by example, exactly what kind of woman you would like her to be.
Personally I think your husband should only get your daughter once every other weekend.
